 * the tool strip are divs and navs, so enumerating prose tags leaves them at
 * full column width.

 *
 * The hero is a sibling of `.wrap`, not an ancestor, so its `overflow: hidden`
 * cannot clip this; and it carries no `z-index`, so `z-index: 5` here paints
 * over it. Both of those are the theme's own assumptions -- `.t33-article-media`
 * relies on exactly the same two facts.
 *
 * The ring in the first shadow is load-bearing, not decoration. The word
 * search board's background is #070b1a, byte-identical to the band's bottom
 * gradient stop (--t33-navy-1), so without a hairline the lifted panel would
 * dissolve into the band instead of sitting on it.
 *
 * `border-radius` is deliberately NOT set: each tool keeps its own (18px for
 * the board, 10px for the drill card), and the word search flattens it to 0
 * when the board goes full-bleed on a phone.
 *
 * `:first-child` is a safety catch, not tidiness. If Journey ever inserts a
 * unit at the very top of `.entry-content`, the tool stops being the first
 * child and the lift drops -- which is the right failure. Without it the tool
 * would keep its -72px and ride up over the ad unit.
