/* Rule the Bar — signed-in WEB app, ported from the live app source.
   Everything here is copied from site/index.html's own <style> blocks
   (tokens, .topbar/.top-progress, nav, .dash-*, .rule-card/.cc-* /.cs,
   .fc-*, .mcq-* and the mcqx- redesign namespace) and assets/fl-materials.css
   (library + reader). Do not "improve" values — fidelity is the point.
   NOTE on the page background: the app's animated .blobs layer is switched OFF
   in the current design (site/index.html line 185: ".blobs{display:none
   !important}" — "New design uses a soft static radial wash instead of the
   animated blobs"). The two radials on .wb below ARE that wash, copied
   verbatim from the app's own body rule. Do not reintroduce blobs.
   Screens render at 1180px and are scaled into a browser frame by --ws. */
