/* ============================================================
   wq-119 — Hybrid redesign (Reader Questions + Reconciliation Spine)
   Local staging styles for the beta/ pages. Layered on top of
   /design-system/colors_and_type.css, ledger-overlays.css and
   assets/wq118-redesign.css (which this file deliberately reuses:
   ribbon, spine, ratio-card, so-what, wwhbt, expand, divider, crumb
   all come from wq118-redesign.css — see deploy record).

   This file adds ONLY the components the question-first architecture
   needs and wq-118 did not have:
     - briefing hero + evidence panel (Overview)
     - five-question card board (Overview)
     - evidence triad (fact / caveat / condition) on ledger pages
     - implication cards (Overview)
   HARD RULE (inherited from wq-118): no new colours, no new type
   families. Every value resolves to an existing design-system token.
   wq-119: question-first with spine module (NOT spine-first wq-118).
