   allrev.app — shared styles (M3.6)

   The tokens below are the desktop app's palette (apps/desktop/src/styles.css)
   reused verbatim: same teal accent, same warm light / cool dark neutrals, same
   radii, focus ring and system font stack (the product ships no webfont). A
   marketing page next to the app should read as its sibling, not a template.

   Differences from the desktop file are deliberate:
     - type scale is web-sized (16px base — this is a page, not a dense tool);
     - theme follows the OS only (no user theme switch on a static page);
     - nothing here is Tailwind — this is plain CSS for a static host.
