/* Structure — the waiting vocabulary.
 * structure-definitions — this file DEFINES the vocabulary; view budgets do not apply.
 *
 * A design system is judged on its loading states more than its buttons,
 * because loading is when the user is least patient and most likely to leave.
 *
 * THE RULE THAT PICKS THE LOADER — match the shape of the wait, not the taste
 * of the designer:
 *
 *   < 300ms   nothing at all. A flash of spinner is worse than a pause.
 *   0.3–1s    inline: the control itself shows it is busy.
 *   1–5s      skeleton in the shape of the content that is coming.
 *   > 5s      determinate progress, with a number, and something to read.
 *   unknown   indeterminate bar at the top; never block the whole screen.
 *
 * WHY SKELETONS DO NOT SHIMMER HERE. The sweeping-gradient shimmer everyone
 * ships is a gradient (forbidden), it moves for decoration rather than
 * information, and it draws the eye to the emptiest part of the screen. A
 * calm opacity pulse says the same thing and says it quietly.

 *      rather than a flash. This is the single highest-value effect here and
 *      it costs nothing but a delay.
 *   3. RESPONSE. Every pressable thing acknowledges the press within 120ms.
 *      Touch UI feels dead almost entirely because nothing answers the finger.
 *   4. CONTINUITY. When a number changes, it counts. When a bar moves, it
 *      travels. The eye follows the change instead of re-reading the screen.
 *
 * Rules that still hold: no gradients, no shadows outside overlays, nothing
 * over 400ms, two easings only, and everything below collapses to a still,
 * legible state under prefers-reduced-motion.
