/* QA Wrap site stylesheet.
   One file, no build step. Every page loads this and thmanyah.css, nothing else.

   The look: "Salsa & Slate, Amman edition" (identity/BRAND.md). Basalt bands
   carry the product (the hero, the trust statement, the footer), limestone
   carries the reading. Petra is for the failure and the one primary action,
   guac for a pass, never decoration. No gradient, no glow, one shadow and it
   is only on the report window that floats. Radii 4 / 7 / 10 / pill.
   Hover changes colour, never geometry.

   WHY the colours are hard-coded: the site deploys on its own, to a static
   host with no access to identity/tokens/tokens.css. The values below are
   COPIED from it (QA Wrap 3.1.0). If that file changes, change these by hand.
   Light and dark follow the tokens; the reader can also pick one with the
   header button (assets/site.js sets html[data-theme]). The basalt bands do
   not change with the theme: they are the product's own ground. */
