/* ==========================================================================
   AWPower Learn — shared design system for the public education pages
   (learn/index.html, hybrid-inverter.html, backup-time.html, your-quote.html,
   faq.html). Standalone: no build step, no src/ imports, no auth, no
   network calls other than Google Fonts + the two logo PNGs.

   Tokens mirror src/styles.css :root and core/report-theme.js — forest
   carries authority, lime is the single energising accent (rules / edges /
   ticks only, never a fill), sage greys + off-whites for everything else.
   Prefixed `--l-` / `.learn-` throughout to avoid any collision with the
   app's own `--aw-` / `.aw-` tokens should this file ever be loaded
   alongside them (it never is, but the app CSS is a shared, fragile file —
   this one deliberately keeps its own namespace).
