/* The landing pages under /for (#535 part 1). Served by routes_landing as
   /landing.css, never inline: production's CSP is default-src 'self' with no
   'unsafe-inline', so a <style> block or a style="" attribute would be dropped.

   The palette is the app's own (web/src/styles.css): the accent is a surface,
   never a text colour, so the button carries --on-accent and links use --ink
   with an underline. The scheme follows the visitor's setting and there is no
   ?theme= override here, so the values are written out twice, light and dark,
   and tests/test_landing.py checks 4.5:1 on every pairing used below. */
