/* WLink — light theme override.
   Loaded AFTER /styles.css. Each page is its own DOM/CSS load, so this is
   opt-in per page rather than global — but it's now the shared light theme
   for the whole product surface (landing, dashboard, builder, register,
   admin, review), not just the marketing site the filename suggests.
   admin/ and review/ used to keep the raw dark tokens in public/tokens/*.css
   unthemed; that was a design-system split, not a deliberate choice, so
   they load this file too now (see DESIGN.md for the rationale).

   Direction: clean, light, professional SaaS — white/soft-neutral ground,
   dark warm-black text, ONE confident accent (a flat, saturated blue) used
   only for the primary action and key highlights. WhatsApp keeps its own
   real brand green so it always reads as "the WhatsApp channel", clearly
   separate from the site's own accent — reinforcing that WhatsApp is a
   secondary channel, not the main call to action. */
