/* ==========================================================================
   Creative Juice Lab — production stylesheet
   "High-precision creative laboratory" — deep indigo surfaces, glassmorphic
   modules, blueprint grid, chemical teal + electric juice orange accents.
   All colors flow through the CSS custom properties set by THEMES in app.js
   (--bg, --bg-card, --bg-alt, --a, --b, --c, --d, --text, --muted, --nav).
   Glass + grid tints are derived from those via color-mix() — no new theme vars.
