/*
 * FlightLab shared theme tokens.
 *
 * flightlab-theme.js (loaded synchronously before this file) sets every token below as an inline
 * custom property on <html> for the active theme, so the :root block here is only a no-JS/first-paint
 * fallback (the default theme, Paper) and documents the vocabulary. Pages must reference tokens, never raw colors:
 *
 *   surfaces   --bg --surface --surface-raised
 *   text       --text --muted --on-accent
 *   sidebar    --nav-bg --nav-text
 *   lines      --border --border-strong
 *   semantics  --accent --accent-2 --success --warning --danger (+ --accent-dim)
 *   alpha mix  rgba(var(--ink-rgb), a)  rgba(var(--accent-rgb), a)  rgba(var(--success-rgb), a) ...
 *   modes      --mode-rocket --mode-airplane --mode-drone --mode-glider --mode-helicopter
 *              --mode-avian --mode-kite --mode-experimental --mode-waterrocket
 *   charts     read through FlightLabCharts / FlightLabTheme, not CSS
