   DESIGN TOKENS
   Exact tokens from the ReturnDeck design handoff (design_handoff_returndeck/
   README.md): maths-paper grid background (25px fine + 125px heavy grid),
   #15181d ink, the four-colour neon "highlighter pack", 2-2.5px borders,
   vertical-only offset drop-shadows (no blur, no horizontal component),
   Space Grotesk / JetBrains Mono / Caveat type stack, rotated sticky-note
   annotations. Colours mapped one-per-content-pillar, same pattern as
   ReturnDeck's CT600 (green) / VAT (blue) / Self Assessment (yellow) cards.
