/* idro-learning.css — IDRO Education shared design tokens
   Phase 4: Section spacing, cards, badges, course/product grids, component panel, CTAs.
   All classes prefixed .idro- or .ilc- to avoid collision with existing styles.
   Uses CSS custom properties defined in :root — does not override global vars.
   No font-face declarations. No color variable overrides. Mobile-first. */
