/* This page no longer mirrors the app's admin palette (it used to copy
   web/static/app.css). It is a marketing surface: deep-navy hero and footer,
   light feature sections, display-scale type — all derived from the same
   brand navy (#1f4e79) as the favicon and the app, so the two surfaces still
   read as one brand without sharing a stylesheet.
   Constraints that shape everything here: the CSP allows only this file
   (no inline styles, no external fonts or assets) and site/check.sh enforces
   the rest — see site/README.md. */
