/* =============================================================================
   lp.css: shared stylesheet for the campaign landing pages (ai-builder-pt,
   lovable-pt, react-spring-boot-pt, clean-architecture-pt, plus the
   lovable-alternative / alternativa-lovable pair served without the extension).

   The design system is the SAME one authored inline in src/landing.html: same
   tokens, same nav, same buttons, same section rhythm. It lives in a separate
   file here because four pages share it, while the home page keeps its inline
   copy: that page is prerendered per language by scripts/build-lang-pages.mjs
   and is not touched by this file.

   Rule of thumb when the home changes: a token or a component that changes
   there has to change here too, or the campaign pages drift visually from the
   product site the visitor lands on next.
