/* Centre Channel — Editorial stylesheet (white ground)
 *
 * Long-form pages on the shop chrome: Thoughts (the library), articles in
 * /insights, the Diagnostic trigger pages, About, Privacy and 404.
 * Loaded after design/tokens.css and assets/shop.css. Consumes the same
 * tokens through the aliases shop.css declares on :root (--ink, --brass,
 * --stone, --charcoal, --mist, --display, --headline, --text-serif, --body).
 *
 * The web3 (dark) class names the pages were written against are mapped
 * here to white-ground equivalents so the markup stays as it was. Classes
 * that only carried a dark effect (bloom glows, reveal fades, centre line,
 * ambient video) are neutralised.
