/* ==========================================================================
   BMTNews stylesheet — editorial redesign (v3)

   Layers, in order:
     1. tokens        — the only place colors/sizes are defined
     2. base          — reset, typography, links
     3. chrome        — header, footer, page intro, skip link
     4. feed          — day stream, toolbar, market strip, filters
     5. story         — digest rows, details, badges, labels
     6. rail          — ranking sidebar
     7. docs/legacy   — notes pages and pre-v2 edition markup
     8. responsive    — breakpoints, reduced motion

   Design rules: hairlines instead of cards, typography instead of pills,
   color reserved for data (score tiers, market up/down) and one ink-blue
   accent. Numbers are always tabular.
