/* ==========================================================================
   Codex 工具箱

   Design read: a maker's software catalog read by people who want a tool and
   nothing else. Calm editorial light page, hairline structure, one accent.
   Dials: DESIGN_VARIANCE 7 / MOTION_INTENSITY 4 / VISUAL_DENSITY 3.

   Rules this file holds to:
   - Page Theme Lock: one theme for the whole page. Sections never invert.
     Dark mode swaps the tokens for the entire page at once.
   - Color Consistency Lock: one accent, saturation 70%, used identically in
     every section. `--accent` is the fill, `--accent-ink` is the readable
     accent for text and icons on the page background.
   - Shape Consistency Lock: one radius, 10px, on every surface and control.
     No pills.
   - No outer glows, no neon, no pure #000, no pure #fff.
