   RobinX — landing and legal pages

   One stylesheet, no JavaScript, no build step. The palette is lifted from the
   app itself (src/theme/colors.ts) so the site and the product look like the
   same thing: the same accent, the same four section hues, the same true-black
   dark mode.

   Every colour pairing here was checked against the app's own contrast test.
   The accent is #2575A9 rather than the logo blue, for the reason the app gives:
   the logo blue reaches only ~2.5:1 on white, which is fine for a mark and
   fails for text.
