/* MuseFrame — gallery stylesheet (2026-10-06 redesign).
   One idea: the page is a gallery wall. Works hang in a mat and a thin frame, each with a small
   wall label (title · exhibition · note). Lots of empty wall. Colour comes from the works; the
   interface stays warm white / ink, with the brand cobalt kept for links and the mark.
   Motion lives here only; JS just adds .js on <html> and .in on revealed elements.
   Everything hidden-before-reveal sits under html.js + prefers-reduced-motion:no-preference,
   so no-JS and reduced-motion readers always get the finished page. */
