+    Subject switcher — the "Parent // Current ▾" page-title dropdown.
+
+    Consolidates the `header-title-dropdown` pattern that was hand-rolled inline
+    across ~18 templates (To-Dos sprint switcher, canvas boards, wiki, ideas,
+    goals, projects…). One place, one markup, reusable.
+
+    Renders an <h1> with an optional parent crumb, a separator, and a Bootstrap
+    dropdown whose toggle shows the current subject. The MENU ITEMS are the
+    slot — each consumer supplies its own <li> options (they carry their own
+    href/onclick), so the switch behavior stays domain-specific while the
+    chrome is shared.
+
+    Keeps the existing classes (.header-title-dropdown, .dropdown,
+    .dropdown-menu) so the established CSS (dropdowns.css) and Bootstrap
+    data-toggle behavior apply unchanged — migrating a consumer is a
+    zero-visual-change swap.
+
+    Props:
+      parent      string|null  Parent crumb label (e.g. "To-Dos"). Escaped by
+                               default; pass an HtmlString/Htmlable if a caller
+                               genuinely needs markup.
+      parentHref  string|null  Optional link for the parent crumb.
+      current     string       The current subject name (escaped — user data safe).
+      separator   string       House-style divider (escaped). Default "/".
+      switchStyle 'legacy'|'pill'  Visual variant. 'legacy' = the established
+                               underlined-caret look. 'pill' is reserved for the
+                               modern treatment (styled in a follow-up); the prop
+                               exists now so it's a one-line flip later.
+
+    Slot: the <li> dropdown-menu items.
