/* ============================================================================
   DinnerDate — public site design system
   dinnerdate.pipchat.in

   No build step, no web fonts, no third-party anything. The CSP on the public
   pages is `style-src 'self'` with no 'unsafe-inline', so there are deliberately
   NO inline style attributes and no <style> blocks anywhere on this site — every
   visual decision lives in this file. Staggered animations use :nth-child rather
   than a --delay custom property set per element, for the same reason.

   Palette is lifted from the app (frontend/src/theme/palette.js) so the web and
   the product read as one brand: flame #F65E3B on warm near-black / warm off-white.
