/* ─────────────────────────────────────────────────────────────────────────────
   robroy.online — shared site stylesheet
   Design tokens lifted from the Station Insight page (the newest generation)
   and generalised so every page on the site shares one system.

   EXCEPTIONS — two pages deliberately keep their own self-contained <style>
   and do NOT read this file: netsolver/index.html (dark landing page with a
   hand-built device mock) and evidr/index.htm (its own type + layout system).
   They were kept because their designs are stronger than the generic template.
   If you change a token here, check those two by hand — they will not follow.

   Per-app identity: an app page overrides --accent/--accent-hover in its own
   <style> block, and MUST declare its dark value inside its own
   @media (prefers-color-scheme: dark) block — a bare :root override would
   otherwise beat this file's dark block on source order and leak the light
   accent onto a black background. See any app page for the pattern.
