+/**
+ * DailyEmberWidget — sidebar gamification card.
+ *
+ * Renders the user's current Daily Ember progress as a small glass-
+ * panel card with a flame icon, "Daily Ember" label, "N / M" current/
+ * max display, ember-gradient horizontal progress bar, and a helper
+ * line. From the operator's redesign-v2 mockup (2026-06-04). Mounted
+ * in Layout.js's desktop sidebar above the user-menu footer.
+ *
+ * The widget consumes `useDailyEmber()` for state; that hook returns
+ * demo data (16 / 20) until the real backend ships in a separate
+ * convoy. See lib/use-daily-ember.js for the wiring TODO.
+ *
+ * Props: none. The component is self-contained on purpose so it can
+ * be dropped into any sidebar variant (mobile drawer, settings page,
+ * future onboarding wizard) without prop drilling.
+ *
+ * Accessibility:
+ *   - The progress bar uses role="progressbar" with aria-valuenow,
+ *     aria-valuemin, aria-valuemax, and aria-label so a screen reader
+ *     announces the current ember count.
+ *   - The flame icon has aria-hidden="true" (decorative; the label
+ *     "Daily Ember" carries the meaning).

+ * redesign-v2 sub-convoy #5 (operator mockup, 2026-06-04). The

+ * matching the mockup (16 / 20). The shape is intentionally stable
+ * so the call-site (<DailyEmberWidget>) never needs to change.

+ * Returns:
+ *   {
+ *     current:    number,   // embers earned today
+ *     max:        number,   // ceiling
