+ISAC Site Controls use collapsible command panels for Launch Gate, Account
+Creation, Public Sections, moderation policy groups, thresholds, and the term
+registry. Build these panels with `CollapsibleSection`. The disclosure button
+must expose `aria-expanded` and `aria-controls`, retain its title and textual
+status while closed, show a focus-visible outline, and provide at least a
+44-pixel touch target. Keep panel content in the document and hide it while
+closed so draft form state survives expansion changes. Disable motion under
+`prefers-reduced-motion`.

+Each command panel owns its save action, validation feedback, pending state,
+and success notice. Do not place a page-wide review or save banner between
+panels. Disable a panel's save button until that panel differs from saved
+state. Saving one panel must update only its fields, retain the panel's open
+state, and leave unsaved drafts in other panels unchanged. Keep `PREVIEW PAGE`
+inside the Launch Gate save row so authenticated operators can inspect the
+promotional page without ending their session. Operators need text for enabled,

+The Site Controls term registry supports single-rule editing and an inline bulk
+editor. The bulk editor accepts pasted lists, applies one effect and scope set
+to the batch, previews the unique-entry count, and states the 250-rule limit.
+Keep it inline because operators need the registry for context. Show exact-word
+behavior beside the textarea, preserve pasted values after validation errors,
+and clear the textarea while keeping the editor open after a successful import.
+Search the registry on the server across term text, normalized text, rule type,

+namespaced URL parameters and 25 rows by default. Search applies before
+pagination. Distinguish an empty registry from a search with no matches. The
+registry toolbar, editors, search, and pagination stay inside the term
