   TECHWAVE ACADEMY CHROME for AI Pulse
   The header, footer, fonts and colour tokens of techwaveacademy.com, so that
   ai.techwaveacademy.com reads as part of the same website. Loaded by every
   page, including the server-rendered /story, /section and /region pages.
   Markup lives in api/shared/chrome.js (static pages carry a copy of it).
   Every selector is prefixed .tw- or .brand-mark so it never collides with
   the page styles in style.css / trust.css.
