/**
 * `tr-embedbadge` — the "Featured on TiorAI" embed block.
 *
 * One bordered panel, split into reading matter on the left and a control panel
 * on the right. Every value is a theme token; the only literals are the three
 * stage fills, which reproduce the badge artwork's own baked-in backgrounds and
 * therefore cannot follow the page theme.
 *
 * BUILT FOR HEIGHT. The first version stacked heading, deck, a 168px
 * checkerboard stage, three bordered variant cards, the snippet and a
 * disclosure, and ran close to 500px on a page that already asks for a lot of
 * scrolling before it. This one is roughly a third shorter: two columns, and the
 * variant choice is one pill row rather than three cards.
 *
 * @package TiorAI

 * LEFT: what the badge IS — heading, deck, and the badge itself on its stage

 * RIGHT: everything you DO — the style pills, the format tabs, the copy button,
 * the snippet, and how to install it.
 *
 * The pills sit with the code rather than with the preview, and the split works
 * because the choice has a visible result on BOTH sides: pressing "Dark" repaints
 * the badge on the left and rewrites the `src` in the snippet on the right, so
 * the control is never acting on something the reader cannot see.
 *
 * `max-width` is off the column: it carries a 260px badge, not just two
 * paragraphs. The deck keeps its own measure instead.
