/* ==========================================================================
   Shared stylesheet for every page that is not index.html.

   index.html keeps its own inline <style> — it is one hand-edited file with a
   large bespoke layout and it is deliberately left alone. Everything else
   (the service pages, privacy, terms, 404) shares this file so there is one
   place to change the sub-page look, and so a returning visitor gets it from
   cache instead of re-downloading it inside every page.

   The palette is index.html's dark brand theme, copied as flat values rather
   than re-derived: these pages have no light theme to fall back from, so the
   two-layer token dance the homepage needs would be noise here.
