/* assets/css/lesson.css
   The shared lesson stylesheet.

   Replaces the per-file inline <style> block. Measured September 20, 2026:
   15 shipped lesson files carry 15 different stylesheets, 2,407 lines total,
   mostly the same rules typed slightly differently.

   Tokens, spacing, and animation curves are lifted from the shipped files
   unchanged, so a lesson built on the runtime looks like the lessons already
   live. Semantic colors follow unlocked-standards-v1.md Section 4. DM Sans is
   the only font, per 5A, and the page loads it. */
