   Core tokens + chrome shared by the secondary pages (transparency, compare,
   about). The home and the older standalone pages (faq/precios/alternativa)
   still embed their own copy of this; new pages link this file instead of
   duplicating ~350 lines each. Page-specific components stay inline per page.
   Matches the home exactly (same tokens, nav, footer, fonts).
