/* ─── Arcos marketing pages (static, under public/) ─────────────────────────
   The shell (header, nav, footer, forms) and the design system that the pages
   ported from catalist.org were written against. Those pages keep only their
   page-specific CSS inline; everything shared lives here, once.

   Palette: the same fixed values as the React landing page (--lp-* in
   src/styles/landing.css). These pages never load the app stylesheet, so the
   values are written out here — keep the two in step by hand. The catalist.org
   variable names (--orange, --navy, …) are kept as ALIASES of the Arcos tokens
   so the ported CSS reads in Arcos blues without a rewrite; re-theming later
   means changing the --as-* block only. */
