/* App-site design system v2 — editorial/product hybrid.
   REPAINT ONLY the :root token block per app (derive from the app's own UI):
   --bg/-soft page ground · --panel(-border) card surface tinted from ink ·
   --ink/-dim text · --accent/--accent-ink CTA · --glow-a/-b hero glow pair ·
   --accent-soft/-faint/--glow-band accent-derived alphas · --header-bg bg-at-78% ·
   --article-ink guide body text · --display self-hosted characterful face (never CDN).
   Everything below :root is the shared component layer: device-frame hero, live-demo
   card, bento grid, editorial guide rows (publish-script contract: .guide-card >
   .tag + h3 + p + .more), FAQ, CTA band, article typography, film grain.
   Fonts: download woff2 subsets (Google Fonts css2 with a browser UA), host at
