/* ============================================================
   /tools/b2b-saas-marketing-channels/ — the quiz + live-rank UI.
   Loaded only on this tool page via its registry `extra_css` entry
   (see tools/_tool-page.php), on top of the sitewide css/tools.css.

   Same rule as tools.css: no new colors, everything below is an
   existing london.css token (--hairline/--tint/--canvas/--brand/--ink/
   --ink-soft/var(--radius)). The 999px pill shape tools.css already
   reserved for "a future progress bar and effort chips" is used here
   for exactly that — the question progress pill and the Q5 multi-select
   chips (styled after the existing .chip component).
