Ft5 · Statement

One large display sentence dominates the footer — a closing line, not a sitemap. Wordmark, minimal links, copyright sit beneath in muted small type. Stripe (older), Mailchimp pre-rebrand, agency portfolio closers. Use when: the page wants a closing line — editorial, manifesto, atmospheric. The sentence pairs with the page's argument. Don't confuse with: Ft1 Mast-headed (which leads with the wordmark, not a sentence).

<footer class="foot-stmt">
  <p class="foot-stmt__line">Build something they'll remember.</p>
  <div class="foot-stmt__meta">
    <span class="wordmark">Studio</span>
    <span class="muted">© 2026 · MIT</span>
  </div>
</footer>
.foot-stmt { padding: var(--space-2xl) var(--page-gutter) var(--space-xl); display: grid; gap: var(--space-lg); }
.foot-stmt__line { font-family: var(--font-display); font-size: clamp(1.75rem, 5vw, 3.25rem); line-height: 1.0; letter-spacing: -0.02em; max-width: 28ch; margin: 0; }
.foot-stmt__meta { display: flex; justify-content: space-between; align-items: baseline; padding-block-start: var(--space-sm); border-top: var(--rule-hair) solid var(--color-rule); }

Anti-pattern: using a Statement footer on a docs root or hub. The sentence reads as marketing fluff there; default Ft3 instead.

    The hallmark skill is a design-focused extension for AI agents that facilitates the creation of professional user interfaces by preventing 'slop' patterns. It provides tools for auditing, redesigning, and studying design elements from screenshots or live URLs. The skill demonstrates robust security awareness, including a comprehensive remote URL safety check and explicit instructions to handle external data as inert to prevent indirect prompt injection. No malicious patterns, such as credential theft, persistence mechanisms, or unauthorized code execution, were identified during the analysis.
