/* ═══ media/pp-lessons.css ═══════════════════════════════════════════════════
   Shared stylesheet for the 19 "Os 44 Sons" lesson pages.

   Extracted 2026-08-07 from a ~250-line <style> block that all 19 pages
   carried inline, hand-copied verbatim into each file (flagged as an
   architectural risk in the card/page element catalogue audit: "any future
   change to the real card CSS will NOT propagate to these 19 pages unless
   someone remembers to hand-edit all 19"). Verified byte-identical across
   all 19 source files before extraction, with exactly one real per-page
   variation point: the --acc/--acc-dim/--acc-glow trio (each lesson's own
   accent color for its phoneme category). That trio is NOT defined here —
   it stays as a small inline :root override in each page, loaded before
   this file has any chance to matter (order is irrelevant either way,
   since this file never defines --acc itself).

   Do not add a --acc value here. A lesson page missing its own override
   would silently fall back to an unset custom property (transparent/
   inherit), which is a louder, easier-to-spot failure than quietly
   defaulting to one specific color that happens to be wrong for 18 of the
   19 pages.
