/* Mobile-only-first. No breakpoints added for desktop layouts on purpose —
   this just stays a centered single column at any width. No webfonts:
   system stack only, so there is nothing to download before text renders.

   Color system: --brand (warm terracotta) drives urgency/CTA; --accent
   (deep teal) drives structure/trust (h2s, section rules, footer). --ink
   is a slightly blue-black, not a neutral gray, so body copy reads as
   branded rather than default.

   Above-the-fold contract (375px): h1 -> CTA block -> short disclosure,
   nothing else. Everything from the emergency banner down is deliberately
   pushed below that block — see renderPage() in src/generate.mjs. */
