   First Wave Discovery — Site styles
   Extends colors_and_type.css. Drives all pages: index, about, services, contact.

   System
   ------
   - Single dark canvas (var(--fw-navy-900)) by default. One optional
     light section (papered) when [data-tweak-light="on"].
   - 12-col implicit; we mostly use flex/grid w/ gap. Page max 1240px.
   - All section padding controlled by --sp-section, scales w/ density tweak.
   - Hairlines + restrained type are the brand voice. No drop shadows on
     primary surfaces; depth via value.
   - Wave intensity is owned by .hero-bg and toggled via [data-tweak-wave].
