/* ═══════════════════════════════════════════════════════════════════════
   Velros Brand — paper / deep-green ink / serif. Canonical: docs/DESIGN.md.
   Tokens are global (brand_tokens.css); the whole app renders on this system.
   `.brand` now only carries the RICH public-page treatment (gradient ground +
   serif) — the app shell uses the flat paper body background.

   COMPONENT LAYER (Tailwind-first policy): the `.brand-*` skin is the public-
   page design system — like the `.btn` system, it's a cohesive set of reusable
   classes, not ad-hoc CSS. It leans on multi-layer gradients, backdrop-filter,
   and untokenized translucent colors that utilities can't express without
   scattering raw colors into markup. Reuse these classes; don't inline-utility
   them. One-off layout/spacing in brand pages still uses utilities.
