/* =========================================================================
   Filament picker, option C (2026-10-16): one line on the page (colour chip,
   material, "Change"), up to six quick picks and a "+N more" sheet with the
   materials down a rail, filters and the colour grid. Shared by the printing
   estimator (React, same class names), /m/ model pages and the models.html
   catalogue modal. Paper look by default; a page can recolour it by setting
   the --fp-* custom properties on .fp (the /m/ pages do, they are dark).
