   Sitewide nav() (2026-09-23) — replaces this deck's own bespoke
   `.site-header` (single WeSurf Desarrollos Sustentables logo, no
   dark/white swap). Its CTA link carries a bare `.btn` class from
   the shared styles.css, which this file's own heavier `.btn` rule
   (margin-top:32px, used by this deck's own CTAs) would otherwise
   clobber once loaded after it — restored narrowly, scoped to the
   nav/mobile-menu only.
