/* site/static/assets/site.css: the landing's one stylesheet (D179), every page and language.
   From the app's homepage (web/welcome.html) and privacy page, moved to a file so the CSP can
   say style-src 'self' (no inline styles). Paper and ink, the red 旅 mark; light by default,
   dark only when chosen (:root[data-theme="dark"], assets/theme-boot.js). No web fonts: the
   system's, with a stack per script (Latin, Japanese, Simplified Chinese) so CJK pages get
   their own glyphs (a Chinese page in a Japanese font shows the wrong forms). Phone first;
   44 px touch targets. */
