   breadcrumb · v1.0.0 · atom

   Where this page sits: the trail of parents above it, each one a link, and
   the page itself last, not a link. Built 2026-10-02 for the Houston Bloom
   spec's part pages (Community Legibility Spec > Programs > Relational
   Spaces), the second surface DESIGN.md asks for before a breadcrumb exists.

   Markup
     <nav class="breadcrumb" data-component="breadcrumb" aria-label="Breadcrumb">
       <ol>
         <li><a href="../cls.html">Community Legibility Spec</a></li>
         <li><a href="../cls.html#parts">Programs</a></li>
         <li><span aria-current="page">Relational Spaces</span></li>
       </ol>
     </nav>

   The separator is drawn by CSS, so a screen reader hears the list and not
   the slashes. The current page is a span with aria-current, never a link
   to itself.

   Token surface, falling back to layer 2:
     --crumb-ink      links                 --color-text-muted
     --crumb-ink-hi   link hover            --color-accent-text, --color-accent
     --crumb-current  the page itself       --color-text
     --crumb-sep      the separator         --color-text-faint
     --crumb-gap      space around it       --space-sm

   data-tone="inverse" is the same trail on a dark ground.

   At 375px: the trail wraps at a separator and never scrolls sideways. A
   long current title wraps inside its own item.
