/* Critical boot shell. Painted from index.html on the very first frame, before
   the JS bundle parses - so there's no white gap and no flash of a text splash.
   Vue clears #sternman and mounts its own, identical-looking app shell
   (.app/.hd/.brand + .loadskel) over it, so the swap is seamless.

   Loaded render-blocking and OUTSIDE the SCSS build, so it can't read the :root
   design tokens (sternman.scss hasn't loaded yet) - every value here is a
   literal copy of a token and must be kept in sync with sternman.scss if those
   change. Kept deliberately tiny (background + masthead brand + skeleton bars;
   the .app compass-rose texture is skipped - imperceptible for a sub-second
   boot). data-theme + data-boot are stamped pre-paint by theme-init.js. */

/* Root font-size baseline: the whole shell below is rem-based on a 62.5% root
   (1rem = 10px), the same value sternman.scss's :root sets - but that stylesheet
   only loads with the JS bundle, so without this the first frame would use the
   16px browser default and every rem here would render ~1.6x too big, then snap
   to size (a zoom flash on reload). theme-init.js also stamps this inline (and
   raises it to 68.75% for the Large text-size setting, which wins over this via
   inline specificity); this is the JS-independent baseline. Keep in sync with
   constants.TEXT_SIZES / sternman.scss. */
