 * The look is the reels' look, from the shoot notes and `storyboard.ts`:
 * off-white, near-black, one accent, no gradients. It must NOT resemble
 * leadoo.net's warm-paper terracotta marketing site — the whole credibility
 * argument for putting these pages on a Leadoo subdomain is that they read as
 * sources rather than as a sales asset, and that job now falls to the design.
 *
 * The organising idea is Vox's: annotated evidence. Citations are not footnotes
 * set small and grey. They are the most distinctive thing on the page, in mono,
 * next to the claim they support.
