/* 趋势看板 — design system.
   Foundation: shadcn/ui "zinc" theme tokens (ui.shadcn.com/r/themes.css) and its component specs
   (button h-9 / badge / toggle group / input / table / card / alert), applied with the Impeccable
   "Operate" rules: one sans family, fixed rem scale, restrained colour (a monochrome UI; colour only
   encodes data), border-only elevation, no side stripes, no decorative motion.

   Colour roles
     UI            background / foreground / muted / border / primary   (shadcn neutrals; primary = ink)
     data          --gold (the series under study) · --blue (context) · --orange (alert)   validated with the
                   dataviz checker on #09090b and #ffffff (CVD ΔE ≥ 22, contrast ≥ 3:1)
     meaning       寒 凉 平 温 热 → diverging blue ↔ orange with a neutral mid; always paired with the character
     text on data  --up / --down / --gold-text are darker steps where plain text needs 4.5:1 on white
   Charts read tokens at render time (tok("name")), so this file is the single source of colour. */
