/* ═══════════════════════════════════════════════════════════════════
   Jetfolio Support Docs — one document treatment
   Design System 2.0 (Phase 7 consolidation)

   Loaded by every reference page under pages/reference/ (the former
   support-docs/guides + regulatory, moved 2026-09-06), after css/tokens.css
   + css/kit.css.

   This file replaced twelve page-local <style> blocks that carried
   four competing templates and a different hero gradient per page.
   The recipe here is the same one the rest of the product uses:
     page ground var(--bg-primary) · white card wells with 1px
     var(--line), var(--radius-lg), var(--shadow-card) · 22px/700
     ink page title · 17px section headings over hairlines · DM Sans
     body held to a readable measure · kit pills for status.
   No gradients, no hero banners — these are reference documents.
