/* ==========================================================================
   ACADEMY V2 LESSON STYLES — append to existing academy.css

   Builds on the existing token system:
     --color-primary, --color-success, --color-accent
     --color-text, --color-text-secondary, --color-text-muted
     --color-bg, --color-bg-subtle, --color-surface
     --color-border, --color-border-subtle, --color-primary-soft
     --radius-sm, --radius-md, --radius-lg, --radius-xl
     --shadow-md, --shadow-lg
     --font-sans, --font-mono
     --track-color, --track-tint  (set per .track-admin/.track-builder/.track-enduser)

   New patterns introduced:
     1. Lesson lead paragraph (above tabs)
     2. Tab strip + tab badges (recorded / soon)
     3. Tab panels (server-rendered, JS-toggled visibility)
     4. Coming-soon banner (per-tab)
     5. Lesson 5-block structure (what / before / do / make-it-real / stuck)
     6. Cold-arrival callout
     7. Checkpoint divider (between Do It and Make It Real)
     8. Make-it-real grid (production hardening cards)
     9. Per-step provider expanders
    10. Pitfall expanders (variant of existing collapse pattern)
    11. Footer card strip (small, three-up)
