   Refined Dark — shared design system (Phase 0)
   Consolidated from teaser_mockup.html + plan_unlocked_mockup.html.
   Every class from both mockups lives here; nothing dropped in the merge.
   Page-specific differences between the two mockups are reconciled under
   the `.page-teaser` scope near the bottom so each page stays pixel-faithful.
