/*
 * REBUILD-BRIEF.md §6 visual identity: deep navy ground, restrained antique
 * gold accent, clean white/ivory controls — the "serious collector's
 * navigation instrument" look, shared across Sign-in, Search, and
 * Instaportal. This is a first, functional pass (layout + the real
 * palette), not the full cartographic treatment §6 also asks for.
 *
 * Colors below reference tokens.generated.css's primitives directly
 * (--color-midnight, --color-gold-500, --color-ivory, --color-steel)
 * rather than its light-mode-default semantic aliases (--color-surface,
 * --color-heading, etc.) — those alias navy to a `.dark` opt-in variant
 * left over from the Tailwind original, and §6 wants navy as the default
 * identity, not an opt-in.
