/* The sieve button's running state — NO SPINNER, AND THAT IS A MEASURED
 * DECISION rather than a shortcut.
 *
 * A CSS spinner was built first: one span, a border and a border-radius,
 * currentColor so it needed no scheme rule, its box reserved with `visibility`
 * so the button could not resize under the cursor. Then it was watched.
 *
 * WHAT THE MEASUREMENT SHOWED. Both scans behind this button run synchronously
 * on the main thread, which is what makes the staged-against-exhaustive
 * comparison like-for-like and is not up for revision. Twelve clipped
 * screenshots of the spinner were taken across a 1.4-second blocked window in
 * HeadlessChrome 149.0.7827.55 on Linux x86_64, and ALL TWELVE WERE
 * BYTE-IDENTICAL — one distinct frame out of twelve. The rotation does not
 * survive the block: it freezes mid-turn.
 *
 * A frozen wheel is worse than no wheel. It is the visual vocabulary of a
 * crashed page, and it would be showing exactly when the page is working
 * hardest. So the rotation was dropped and the element with it, rather than
 * shipping a static ring that reads as a hang.
 *
 * What is left is the state itself, which needs no motion to be legible: the
 * label changes, the button is disabled, aria-busy is set, and this rule makes
 * the disabled state visible — css.css styles no :disabled at all, so without
 * it a disabled button is pixel-identical to a live one.
