/* ReuseForge design system (rf.css). Living reference: /design/ and docs/DESIGN_SYSTEM.md.
   Principles: a ledger for code. Cool iron neutrals, one ember accent, hairlines instead of shadows,
   tabular mono for money, hashes and ids. Geist (self-hosted) for text, system CJK fonts for Chinese.
   Token names --bg --side --panel --panel2 --fg --mute --faint --line --line2 --acc --acc-fg --acc-soft --ember --good --bad --warn --info --r --sans --mono
   are a stable contract: app and page CSS may rely on them. Everything else is additive. Never rename or remove a class.
   Dark mode: follows the OS, override with <html data-theme="light|dark">. CSP: no inline styles; widths come from --v (see data-v in rf.js). */
