/* Brick Auction landing — long-form content pages.
 *
 * Loaded ONLY by the editorial/legal pages (/reverse-auction, /green-paper,
 * /about, /supplier, /terms, /privacy, /price-list, /brick/*) on
 * top of styles.css. It has no overlap with shop.css, so a page loads one or
 * the other, never both — except /brick/<slug> and /price-list, which need
 * shop.css too for the product grid.
 *
 * Everything here is prose furniture: a readable measure, headings, tables,
 * callouts and a table of contents. It deliberately introduces no new colour
 * tokens — every value below resolves through the --brand-*/--surface-* scale
 * already declared in styles.css.
