/* pmg-template-browser.css (tb-1, 2026-05-23)
 *
 * Styles the Template Browser modal launched from the chassis-v3 nav
 * (#pmg-template-browser-btn between Vault and Expert). All values use
 * --color-* / --radius-* tokens from pmg-g-theme.css. No hardcoded hex.
 *
 * z-index 100050 sits above the chassis-v3 topbar (10010), the splash
 * (99999), and below the live upgrade modal (100001). Backdrop is full
 * viewport, dark, with a subtle blur.
