/* ============================================================
   Working Ledger — blog + live-demo theme extension
   (blog/* EN+ES incl. index, demo/index EN)
   Loads AFTER /css/ledger.css (tokens, fonts, body, .btn base).
   Replaces 14 divergent legacy inline <style> blocks with one
   alias layer: legacy token names map onto ledger tokens so
   page markup stays untouched (pure head swaps).
   Brand refs: reports/brand_identity.md §2 palette, §3 type,
   §4 layout rules (no centered hero / equal-card SaaS look).
