/* src/styles/tokens.css
 * Root design tokens, reset/base, tabular-numerals helper, and the two fixed
 * background layers (app-bg / app-grid). Ported verbatim from the Emberly
 * Control Room stylesheet (site/index.pretty.css lines 1-72) — see
 * part3-visual-system.md §1 (Tokens, fonts, base/reset, scrollbars).
 *
 * Font note (verbatim behaviour, part3 §1.0): Inter is *declared* in --font
 * but never loaded (no @font-face / @import / <link>) in the original app,
 * so it renders in Inter only on machines that already have it installed and
 * falls back to the system UI font everywhere else. This file intentionally
 * does NOT add a Google Fonts (or any) import, to match that behaviour.
