/* ---------- 6. Waivers (logged inline per design system §waivers) ---------- */
/* WAIVER: existing inline base.html styles use Montserrat/Poppins font stack
   and non-Fibonacci spacing throughout. Round 1+2 retrofit overrides
   typography globally + spacing/colors per-section. Full inline-style purge
   is out of round 1/2 scope and would force visual regression on the other
   6 tabs which are deliberately untouched.

   ROUND 2 NOTE (Workflow / Booking System / Comms): two of these sections
   (Workflow, Comms) host iframes (ClickUp + Slack respectively). Iframe
   content is sandboxed and cannot inherit our typography or color tokens.
   Pillar 3 retrofit applies to the CHROME around the iframe (section header,
   toolbar buttons, surrounding panels) — the iframe content itself remains
   provider-styled. This is correct behavior, not a gap. */
