   THEME TOKENS

   LIGHT is the default. Dark is opt-in via the header toggle and
   remembered per visitor (localStorage "rb_theme").

   To flip the default back to dark, swap the two selectors below:
   put the dark values on :root and the light ones on
   :root[data-theme="light"], then update the two `currentTheme`
   defaults in js/main.js and the <meta name="theme-color"> values.

   Two things deliberately stay dark in BOTH themes:
     · the hero — it is a brand panel, and the glow only reads on dark
     · the lightbox — photo viewers are dark everywhere, for good reason
