/* ─────────────────────────────────────────────────────────────────────────
   StoreSum — public marketing site.

   One stylesheet for every page. No build step and no framework, deliberately:
   this repo is meant to be edited by hand in a future session, and a static
   site Hostinger serves straight from git has nothing to break at deploy time.

   Tokens: light is the base. Dark redefines ONLY tokens — once for the
   un-stamped system-preference state, once for an explicit toggle — so a
   colour is never defined solely inside a media query.
