/* Shared styling for the standalone pages on plusheat.io — /privacy, /support
   and the 404.

   These three used to carry ~10KB of near-identical CSS inline, three copies
   that had already drifted: the measure was 760px on one and 720px on the
   others, the h1 was a fixed 40px on one and fluid on the others, and only one
   had a media query. Same palette in all three, so the drift was structural
   rather than visual, which is the kind that creeps.

   apps/landing has no build step — deploy-frontends.yml uploads the directory
   as-is — so a plain stylesheet linked with an absolute path is the whole
   mechanism. Absolute, not relative, because /privacy/ and /support/ sit one
   directory deeper than 404.html.

   The marketing homepage (index.html) is deliberately NOT on this: it is a
   different kind of page with its own art direction, and pulling it in here
   would mean this file has to serve two masters. */
