/* Root overlay — self-contained (CIModal toggles display:flex/none via inline style).
   z-index MUST stay 1065 — strictly ABOVE the shared CIModal `.modal-backdrop`
   (assets/css/components/modal.css: z-index 1055, backdrop-filter: blur(4px)).
   CIModal.show() appends that .modal-backdrop to <body>; at an equal z-index the
   backdrop (later in DOM order) paints ON TOP of this dialog, and its
   backdrop-filter then samples+blurs the dialog text behind it — the exact "fuzzy
   modal" symptom reported on the landing page — while also intercepting pointer
   events on the close button and links. Sitting one layer above (1065, matching
   the generic `.modal` token) makes the dialog paint above the backdrop so it
   renders crisp and stays clickable. The dark ::before scrim below is a fallback
   for the manual (non-CIModal) open path in landing-enhance.js, which creates no
   .modal-backdrop of its own. */
