/* ==========================================================================
   STUDIO PROJECT PAGES — shared chrome + long-scroll rhythm.
   Each project (easy-gas / fatima / terra) sets --proj-color and otherwise
   reuses this file entirely; page-specific copy/images live only in the
   HTML. No header, no footer — just the two controls the brief calls for.
   Real scrolling is allowed here (unlike studio.html itself).
