/* ============================================================
   SILICON HARBOR — site extensions.
   styles.css is the approved reference stylesheet and is FROZEN
   (the hero lives there, byte-identical). Everything new — header,
   footer, subpages, ported effects — lives here and never touches
   the hero.

   THE TRACE ALPHABET (restored by collation, 2026-07-10 debate —
   not invented; each glyph already existed in the manuscript):
     hairline  1px accent rule ......... styles.css:94  (.eyebrow::before)
     hair,vert 1px × 34px .............. styles.css:86  (.scrollcue span)
     dash      14px × 1px list marker .. site.css (.case li::before)
     dot       5px accent circle ....... site.css (.band-item.dot)
     node      11px ring, 1.6px accent . site.css (.mapnode::before)
     stem      15px × 1px connector .... site.css (.mapnode::after)
   These six are the ONLY line-and-marker system on this site.
   Icon libraries are forbidden. Radii: 6 / 0 / 100 only.
   Numbers ship un-rounded, witnessed, and dated (see WITNESSES.md)
   or they do not ship. No unwitnessed future tense. Inter is
   self-hosted; no page may call a third-party host.
   Slop moves everywhere because it is afraid; confidence stands still.
