   Shared base used by every page: reset, navigation, language selector, and
   footer link group. These rules were byte-identical across all pages and are
   now centralized here. Page-specific styles (hero, sections, buttons, etc.)
   remain in each page. Link this BEFORE any page-specific styles.
