Craft Standards

The super-quality bar for Design, Animation, and Branding axes. These are the standards funnel premium enforces upstream of and across Stages 4–7. Lighthouse and WCAG are the floor — this document defines the ceiling.

A landing page that hits the perf budget but feels generic loses to a landing page that hits the same budget and feels inevitable. Craft is the difference.


Design Discipline

1. Visual Hierarchy Rubric

Score each LP from 0–3 per criterion. Ship target: ≥ 20/27.

Criterion 3 — Excellent 2 — Good 1 — Weak 0 — Broken
Hero-Contract Legibility What / for whom / why-now answerable in ≤ 5 seconds 6–8 seconds 8–12 seconds Not answerable
Primary focal point Single, unmistakable focal point above fold One focal point with some competition Multiple competing elements No focal point
Scale contrast Hero element ≥ 3× secondary 2× contrast 1.5× contrast Flat
Weight contrast Bold vs. regular vs. light used purposefully Two weights with clear roles Inconsistent weight use Single weight everywhere
Color hierarchy Accent reserved for actions/highlights; neutral palette carries body Mostly disciplined Accent overused Accent everywhere
Whitespace rhythm Section padding follows tokens; breathing room around CTAs Mostly consistent Cramped or arbitrary No system
Scan-pattern coherence Layout matches chosen pattern (F / Z / Layer-cake / Centered / Card-grid) per ia-blueprint.md Mostly aligned Some misalignment Random placement
Section identity Each section visually distinct yet cohesive Mostly distinct Sections blur into each other All sections look the same
Mobile fidelity Mobile is designed, not shrunk; tap targets ≥ 44×44 px; thumb-zone aware Adapted; targets ≥ 40 px Reactive only Broken on mobile

2. Typography Craft

  • Type scale: modular (e.g., 1.25, 1.333, 1.5 ratio). Document the ratio in tokens.json. No off-scale sizes.
  • Display headline: 1 family, 1–2 weights. Optical sizing if variable font. Pair with body for clear contrast (serif↔sans or display↔text).
  • Body line-height: 1.5–1.7 for paragraphs, 1.2–1.35 for headlines, 1.1 for display.
  • Measure (line length): 45–75 characters for body. Enforce max-width per breakpoint.
  • Kerning + balance: text-wrap: balance on headlines; text-wrap: pretty on paragraphs (where supported, with fallback).
  • Variable font axes: use weight/optical-size/slant axes when available; ship single woff2 file under 100KB subsetted.
  • Numerical typography: tabular numerals for pricing, stats, dashboards (font-variant-numeric: tabular-nums).
  • 2026 trend awareness: kinetic typography on hero (animated weight/width shift), pair with reduced-motion fallback.

3. Color Discipline

  • Token-only: zero hardcoded color values in production code. Enforced at Build gate.
  • Semantic naming: --color-action-primary not --color-blue-500. Surface vs. ink vs. accent vs. status.
  • Contrast ratios:
    • Body text: ≥ 4.5:1 (AA)
    • Large text (18px+ bold or 24px+): ≥ 3:1 (AA)
    • UI components / focus indicators: ≥ 3:1 (AA)
    • Stretch target: AAA where feasible (7:1 body, 4.5:1 UI)
  • Color blindness: verify against Deuteranopia + Protanopia + Tritanopia simulators; never rely on color alone for state.
  • Dark mode: if in scope, use color-mix() for tonal variants; preserve hierarchy across modes.
  • Gradient usage: purposeful, brand-coherent. Banned: rainbow gradients without semantic anchor. Encouraged: 2-stop subtle gradients on hero, mesh gradients with motion budget.

4. Whitespace Rhythm

  • Section vertical rhythm: based on a spacing scale (4 / 8 / 12 / 16 / 24 / 32 / 48 / 64 / 96 / 128 px). Tokenized.
  • Above-fold spacing: hero copy ↔ CTA ≥ 24px; CTA ↔ trust strip ≥ 32px.
  • Section padding: 64–128px desktop, 40–80px mobile, scaled by content density.
  • Microspacing: 4/8/12px between elements within a card; never arbitrary margin: 11px.

5. Detail Craft

The differentiator between B+ and A+ LPs:

  • Cursor states: every interactive element has a hover + focus + active state. No cursor: default on buttons.
  • Focus rings: visible, branded, AA contrast against any background.
  • Empty states: every list / search / filter has an explicit empty state with copy + illustration.
  • Loading states: skeleton screens for any content > 100ms; spinner only for genuine indeterminate wait.
  • Error states: every form field has specific error microcopy (Prose), never "Invalid input".
  • Icon system: single icon family (Ink-produced or curated set). Stroke weight matches typography weight. Pixel-aligned at 16/20/24/32.
  • Image craft: every hero / lifestyle / illustration has intentional crop, focal point, exposure consistency. No stock-photo bingo.

6. 2026 Design Trend Calibration

Read awareness, not mandatory adoption. Apply only when brand and audience justify.

Trend When to adopt When to skip
Liquid Glass / dimensional UI Premium hardware / consumer apps / luxury B2C Trust-critical B2B (banking, healthcare)
Kinetic typography on hero Brand-led launches, creative-industry, design tools Calm UI / clarity-led / accessibility-critical
Mesh gradients + organic shapes Modern SaaS, creator economy, lifestyle Enterprise SaaS / professional services
Brutalist editorial Strong-POV brands, agencies, niche communities Mass market / conversion-first
Calm UI / generous whitespace Trust-critical (legal, finance, health, premium) Direct-response / high-urgency campaigns
3D / Spline / interactive demos Product-led demos, hardware showcases Performance-budget-constrained pages
AI-driven adaptive UI SaaS with rich behavioral data, ecom personalization Trust-critical / fixed-message brand launches
Variable-font dynamic typography Modern editorial, brand-led design tools Multi-locale LPs (subsetting complexity)
Spatial / Z-axis layering (non-XR depth) Premium hardware, creative tools, design portfolios Information-dense B2B / dashboards
Anti-AI-look / human craft signaling Heritage brands, craft / artisanal, anti-tech positioning AI-native products (counter-message)

Mandatory rule: when adopting AI-driven adaptive UI, an explainability affordance ("Why am I seeing this?") must be present and tested. This is gate-checked at DESIGN exit when the trend is in scope.


Animation Discipline

1. Motion Tokens

Define in tokens.json under motion.*:

{
  "motion": {
    "duration": {
      "instant": "75ms",
      "fast": "150ms",
      "base": "250ms",
      "slow": "400ms",
      "deliberate": "600ms"
    },
    "easing": {
      "standard": "cubic-bezier(0.4, 0, 0.2, 1)",
      "decelerate": "cubic-bezier(0, 0, 0.2, 1)",
      "accelerate": "cubic-bezier(0.4, 0, 1, 1)",
      "emphasized": "cubic-bezier(0.2, 0, 0, 1)",
      "spring-snappy": "linear(0, 0.5 25%, 1 50%, 0.85 65%, 1)"
    },
    "stagger": {
      "tight": "30ms",
      "comfortable": "60ms",
      "dramatic": "120ms"
    }
  }
}

2. Motion Principles

Principle Rule
Purpose Every animation answers: orient (where I am), feedback (what happened), delight (brand). No motion without one of these.
Speed UI feedback < 200ms. Section transitions 250–400ms. Hero/atmospheric ≤ 600ms. Never longer unless cinematic and skippable.
Easing Standard easing for most. Decelerate for entrances. Accelerate for exits. Emphasized for hero moments. Spring for playful brand. Never linear (except progress).
Choreography Coordinated, not chaotic. Stagger reveals 30–120ms; one element starts, the next begins as the first crosses ~60% progress.
Direction Motion direction matches information flow. Top-to-bottom for new content; left-to-right for forward; right-to-left for back.
Reduced motion @media (prefers-reduced-motion: reduce) removes parallax, autoplay, infinite loops, attention-grabbing motion. Functional transitions can keep 100ms cross-fades.
Performance Animate only transform, opacity, filter. Never layout-triggering properties (width/height/top/left).
INP budget (HARD CEILING) Motion contribution to INP ≤ 50ms is a hard ceiling, not a rubric criterion. Failure to meet it triggers immediate Flow+Bolt repair (see quality-gates.md Oscillation Guard); motion rubric scoring continues only after the ceiling is met.

3. Motion Patterns (named, reusable)

Pattern Use Implementation
Hero entrance Above-fold reveal Stagger headline → sub → CTA → hero asset; decelerate 400ms
Section enter Scroll-into-view IntersectionObserver fade-up 24px, decelerate 300ms, once
Scroll-driven progress Page progress, parallax CSS animation-timeline: scroll() — no JS scroll listeners
CTA hover Buttons / cards 150ms transform scale 1.02 + shadow lift
Form feedback Input focus / error 200ms outline + 75ms shake (errors only, 1 cycle, low amplitude)
Modal / sheet Overlay panels View Transitions API where supported; fallback to 250ms slide+fade
Loading skeleton Async content Subtle linear gradient sweep, 1.5s loop, paused under reduced-motion
Counter / stat reveal Numbers in social proof requestAnimationFrame ease-out 800–1200ms, observed once
Microinteraction confirm Successful submit / copy / save 250ms checkmark draw + 600ms bloom + auto-dismiss

4. Tool & Format Choice

Asset Tool Format When
Simple UI motion CSS / WAAPI n/a Default for transforms, opacity, focus, hover
Scroll-driven Native CSS animation-timeline n/a Modern browsers; no JS scroll listeners
Complex character / illustration Lottie .lottie (dotLottie) Hero motion, brand mascot
Interactive vector Rive .riv State-machine driven, lightweight
Page transitions View Transitions API n/a SPA navigation, multi-step forms
3D / dimensional Spline / Three.js embed / canvas Premium product demos only
Video background .mp4 + poster h.264 + AV1 Atmospheric hero, with reduced-motion fallback

5. Motion Quality Rubric

Ship target: ≥ 15/20.

Criterion 4 — Excellent 3 — Good 2 — Weak 1 — Broken
Purpose clarity Every animation has a reason Most do Some decorative-only Motion for motion's sake
Choreography Sequenced reveals feel composed Mostly coordinated Some clashes Everything moves at once
Easing fit Easing matches motion type Mostly Some linear All linear
Reduced-motion respect Full alternative path Most paths Partial Ignored
Performance All on compositor; INP ≤ 200ms Mostly Some layout-triggering Jank visible

Branding Discipline

1. Brand System Anatomy

Before any LP design, the brand system must be defined or referenced. Missing pieces → ask user or escalate to Vision/Saga. Vision authors the Voice_Spectrum; Prose executes voice in copy.

BRAND_SYSTEM:
  Promise:
    Statement: "<the one-sentence outcome the brand delivers>"
    Type: "Functional | Emotional | Self-Expressive | Aspirational"
  Story:
    Hero: "<customer is the hero — OR — guide-as-hero for technical-developer / category-creator brands>"
    Guide: "<brand is the guide>"
    Problem: "<external + internal + philosophical>"
    Plan: "<3-step path>"
    Success: "<vivid after-state>"
    Failure: "<vivid stakes>"
  Positioning:
    Category: "<the category the brand competes in>"
    Differentiator: "<what makes it different>"
    For_Whom: "<primary audience>"
    Against_Whom: "<the alternative being displaced>"
    Anti_Archetype: "<what the brand explicitly is NOT — sharpens differentiation>"
  Verbal_Identity:
    Tagline: "<≤7 words, ownable, brand-voice-loaded — Saga + Prose>"
    Naming_Pattern: "<product nomenclature rule — e.g., verb-led, mythic, kebab-noun>"
    Claim_Ladder: ["<top claim>", "<supporting claim>", "<proof point>"]
    Big_Idea_Owner: "Compete + Funnel"
    Tagline_Owner: "Saga + Prose"
    Visual_Claim_Owner: "Vision"
  Voice_and_Tone:
    Personality: ["<3-5 adjectives>"]
    Voice_Spectrum:                          # Vision authors
      Formal_to_Casual: "<0..10>"
      Reserved_to_Enthusiastic: "<0..10>"
      Serious_to_Playful: "<0..10>"
      Mainstream_to_Bold: "<0..10>"
    Always_Say: ["<patterns>"]
    Never_Say: ["<anti-patterns>"]
    Tone_Variants:                           # Prose executes — DESIGN gate verifies all 5 are drafted
      Hero: "<bold, declarative>"
      Pricing: "<clear, no hedging>"
      Errors: "<helpful, never shaming>"
      Empty_State: "<warm, directive>"
      Legal: "<plain, scannable>"
  Visual_Identity:
    Archetype: "<Magi | Hero | Outlaw | Magician | Everyman | Lover | Jester | Caregiver | Ruler | Creator | Innocent | Explorer | Oracle/Agent | Operator>"
    Secondary_Archetype: { archetype: "<one of above>", mix_ratio: "70:30 | 60:40 | none" }
    Mood: ["<3-5 keywords>"]
    Color_Story: "<warm/cool/neutral + accent strategy>"
    Type_Story: "<display + body pairing rationale>"
    Image_Style: "<photography vs illustration vs 3D + treatment>"
    Image_License_Posture: "Commissioned | Licensed-stock | AI-generated | Mixed"
    Motion_Story: "<calm vs energetic vs precise vs playful>"
  Accessibility_Stance:
    Baseline: "WCAG 2.2 AA"
    Stretch: "AAA where feasible"
    Motion_Budget: "<reduced-motion mandatory; rich-motion default = on/off>"
  Evidence_Bank:
    Numeric_Proof: ["<stat with source and date>", ...]
    Named_Customers: ["<logo + outcome>", ...]
    Awards_Press: ["<source>", ...]
    Author_Authority: { person: "<name>", credentials: "<list>", sameAs: ["<LinkedIn>", "<ORCID>", "<Wikidata>"] }

Two added archetypes for 2026 LPs:

  • Oracle / Agent — AI-native brands whose promise is autonomous outcomes; requires explainability affordance ("Why am I seeing this?") in any AI-driven adaptive surface.
  • Operator — Linear / Stripe / Vercel cluster: Magi authority + Creator precision with deliberate personality restraint. Distinct from Magi in restraint discipline.

2. direction.md Minimum Payload Contract

When Vision emits direction.md to Muse, the file MUST contain (else Muse rejects and returns to Vision with a brand recipe):

# direction.md

## Archetype
Primary: <archetype>
Secondary (optional): <archetype> mix <ratio>
Rationale: <2-3 sentences>

## Mood
Keywords: <3-5>
Reference moodboard: <path or links>

## Type Direction
Display family + weights: <names>
Body family + weights: <names>
Scale ratio: <e.g., 1.25 / 1.333 / 1.5>
Variable-axis usage (if any): <wght / opsz / slnt>
Kinetic typography: <on/off + scope>

## Palette Intent
Strategy: <warm/cool/neutral + accent strategy>
Surface ↔ ink contrast target: <AA / AAA>
Dark-mode posture: <single-mode | auto-switch | manual-toggle>

## Motion Intent
Motion story: <calm | energetic | precise | playful>
Weave: <duration baseline e.g., 250ms>
Reduced-motion alternative declared: yes/no

## Scan-Pattern Preference
Primary pattern: <F / Z / Layer-cake / Centered axis / Card grid>
Rationale: <why this matches archetype + persona>

## Asset Direction
Image style: <photography / illustration / 3D / mixed>
License posture: <commissioned / licensed-stock / AI-generated>
AI-driven adaptive UI: <on/off; if on, explainability indicator location declared>

2. Brand Voice Application

Voice = consistent personality across all copy. Tone = situational adjustment.

  • Hero: highest brand voice expression. Bold, distilled, memorable.
  • Body benefits: voice slightly dialed back for clarity. Specifics + outcomes.
  • Microcopy / errors: tone shifts to helpful + warm. Voice still present but quiet.
  • Legal / footer: plain language, voice barely visible, but never robotic.

Prose owns voice execution. funnel premium confirms the brand system is referenced.

3. Positioning Discipline

Use Compete's positioning map output. The LP must:

  1. Name the category the brand operates in (explicit or implicit, never both unclear).
  2. Make the differentiator visible above the fold or by section 2.
  3. Address the "against whom" frame in objection handling.

Anti-pattern: feature-list LP that competes on parity instead of positioning.

4. Brand Coherence Check (Verify stage)

Three-channel coherence audit:

Channel What to check
Visual Token usage matches brand archetype. Imagery treatment matches image style. Motion matches motion story.
Voice Sample 10 copy strings across LP. Score each on the voice spectrum. Variance < 1.5 points per axis.
Experience Form fields, micro-interactions, success states all reinforce brand personality. Errors don't break voice.

A regression on any channel = repair before Launch.

5. Brand Quality Rubric

Ship target: ≥ 17/24 (6 criteria × 4 points).

Criterion 4 — Excellent 3 — Good 2 — Weak 1 — Broken
Promise clarity One-sentence test passes in 5 seconds Mostly clear Hedged or generic No discernible promise
Voice consistency All copy reads as one author (variance < 1.5 per spectrum axis) Mostly Some inconsistency (variance 1.5–2.5) Multiple voices clash (variance > 2.5)
Positioning crispness Category + differentiator + against-whom + anti-archetype clear Mostly Two of four None visible
Visual coherence Archetype (incl. secondary mix) reads in <3 seconds Mostly Mixed signals No archetype
Story echo Hero arc visible (customer-as-hero by default; guide-as-hero acceptable for technical-developer brands when declared in Brand System) Mostly Implicit only Brand-as-hero anti-pattern
Trust-signal density ≥3 trust mechanics surfaced by section 2 (named-customer outcome / numeric proof / press / open-source / guarantee / author authority) 2 mechanics 1 mechanic None — brand asks for action without credibility

Cross-Discipline Coordination

These rules govern how Design, Animation, and Branding stay aligned:

  1. Brand system precedes design tokens. Vision + Saga define brand before Muse generates tokens. Tokens must encode brand decisions, not the inverse.
  2. Motion story comes from brand archetype. A "Magi" brand uses deliberate, calm motion; a "Jester" brand uses snappy, playful motion. Flow consults Vision's direction.md before authoring motion tokens.
  3. Design rubric scoring happens before Build. No production code on a < 18/24 design or < 15/20 motion or < 14/20 brand score. Repair or escalate.
  4. Detail craft is the Verify checklist's secret tier. Judge re-walks for cursor states, focus rings, empty states, loading states, error states, icon consistency, image craft. Anything missing = P2 finding.

Six-Axis Ownership + Ship Rubrics (SKILL.md excerpt)
