/* DiveLog shared modal dialog. Drives DL.Modal.confirm / DL.Modal.alert.
 *
 * Self-contained: doesn't depend on /stat/stat.css or any module CSS.
 * Chrome uses the shared :root theme tokens (--bg-card, --border, …) so
 * the dialog matches whatever theme is active.
 *
 * Overlay layering, highest last: .dl-header 1000 < .stat-modal 1100 <
 * .chart-modal 1200 < .dl-modal 1300. This dialog is top of the stack so a
 * confirm asked from inside another modal still surfaces on top, and every
 * full-viewport overlay clears the sticky app header. */
