/* Mutabloom — the whole site's styles.

   Every page links this file, including the landing page. That is a deliberate difference
   from the older sites here, where the landing page kept its styles inline and the palette
   was therefore written down twice; the second copy drifted the first time a colour changed.
   One file, one palette, four pages.

   The direction comes from MUTABLOOM_PLAN.md sections 5.2 and 5.4, so the site reads as the
   same object as the game: soft rounded low-poly shapes, hand-painted gradient light, pastel
   meadow greens, and one warm rim light doing the accenting. SF Rounded for display and SF
   Pro for body, both through system stacks -- no web font is loaded, so nothing here can be
   slow, blocked, or a third party watching who read the privacy policy.

   No JavaScript anywhere on this site. There is nothing here that needs any. */

/* ---- Palette ----------------------------------------------------------------------
   Light is the default and is defined in full on bare :root, so a browser that reports no
   preference still gets a complete set of colours rather than half of one. Dark mode
   redefines the same tokens and nothing else. */
