/* ============================================================
   BLUE PRINCE BOARD GAME — SHARED SITE STYLES
   blueprinceboardgame.com

   ARCHITECTURE (Phase 1 — design tokens)
   -----------------------------------------------------------
   Token system uses primitive -> semantic layering:
     - Primitive tokens are raw values (--navy-900, --gold-700)
     - Semantic tokens reference primitives for purpose
       (--color-bg-hero references --navy-900)
   Change a primitive and every semantic derivation updates.

   LEGACY ALIASES preserved: --bg, --navy, --gold, etc. Keeps
   inline styles + unmigrated CSS working unchanged.

   COLOR MIXING: tints/shades are derived via color-mix() in oklch
   (Baseline Widely Available as of 2026 — perceptually uniform,
   so derived tints read natural). Preferred over ad-hoc rgba()
   because it's one source of truth from the primitive color.

   NOTE — cascade layers (@layer) were considered but removed:
   they caused regressions on pages with inline resets like
   '* { padding: 0 }', because unlayered styles win over layered
   ones. Traditional specificity-based cascade is the safer
   model when inline <style> blocks are common. Tokens alone
   already give the maintainability benefit the cleanup aims for.

/* ============================================================
   BLOG POSTS (Dev Log articles)
   Shared layout and components for /post-*.html pages.
   Post-specific styles (delta-table, error-table, change-list,
   decorative callouts) remain inline in each post. Older posts
   that use a narrower 780px layout keep that width override
   inline — a visual standardization pass is deferred.

   NOTE: post pages include `body { padding-top: 0 !important }`
   inline to remove the default top gutter — not hoisted here
   because it would affect every page, and only post pages need it.
