/**
 * BrandFrame — styles (DESIGN.md reskin).
 *
 * Shared GeezWord/GeezSoft brand bar. Reskinned to the DESIGN.md system:
 * parchment / indigo tracks, Fraunces + Newsreader + Noto Serif Ethiopic
 * type, the §3a foundational palette. Structure is unchanged — sticky bar,
 * brand pill, "geezword.com →" cross-link, Habi mascot, four tracks.
 *
 * Habi stays the same character illustration; only the brand pill colour
 * varies per app (signatureColor, mapped to DESIGN.md §3a tokens).
