/* Kid & Kid marketing site. Static, no script (CSP script-src 'none'): every effect here is CSS,
   and the moving pets are animated WebP pictures baked from the game's own animations
   (scripts/build_site_assets.py). No inline styles either (CSP style-src 'self').
   The look is the game's: its lavender background with soft bubbles, its font (Fredoka), its
   chunky outlined buttons and the four colours of the logo (cyan, yellow, pink, purple).
   Cache-busting: the pages link this file as site.css?v=<date>; bump that in every page after
   an edit (grep "site.css?v=" in site-src/pages/, then scripts/build_site_pages.py).
   LANGUAGES (docs/languages.md): the pages exist once per language (site/<code>/); Persian,
   Arabic and Urdu are right-to-left, so sides are written as start / end (text-align: start,
   margin-inline, inset-inline-end), never left / right, except for pure decoration. */
