/* Web-only design layer.
   =========================================================================
   Loads AFTER theme.css, which is a verbatim copy of the extension's design
   system and the source of truth for every shared colour (product law 6,
   enforced by tools/sync-theme.mjs and the static checks).

   Nothing here redefines a canonical colour. This file adds only what a
   marketing site needs and an extension popup does not: display type, radii,
   elevation, glows, and the page gradient. Every value below is either new,
   or derived from a canonical token so the two can never disagree.

   If you want a different blue, or a deeper dark background, change it in
   attention_pro_extension/theme.css so all three surfaces move together.
   Overriding it here would make the website the odd one out.

   strange thing for a site whose main claim is that detection runs on your

   missing the stacks below fall through to the system fonts and the page is
   still perfectly readable. */
