/* ===== sharper.academy, brand v5 (glass) =====
   One stylesheet for every page. Values come from /assets/brand/tokens.css, pulled from the
   sharper-ai/sharper-brand repo by scripts/pull-brand.mjs; nothing here invents a colour.
   The tokens below are semantic, as in the guide's Design system: the same names on night and on
   white, so a white section (.paper) is the same components with the tokens flipped.

   Grounds: night is the page. .raised steps forward from it. .paper is a white band, for long
   reading, data and forms, print, and to break up a dark page. .violet relights a section in violet,
   which the site keeps for its one sub-brand, AI Adoption, Live. */
