+feat(page,element): declare inputs for the eight configurable page:\* / element:\* blocks
+
+Same gap objectui#3027 closed for `record:*`, in the two namespaces next door:
+renderers that read real props while every authoring surface reported "takes no
+configuration". Declarations mirror what each renderer reads —
+
+| block | inputs |
+|---|---|
+| `page:tabs` | items, tabStyle (line/card/pill), position (top/left) |
+| `page:card` | title, bordered, body (slot), footer (slot) |
+| `page:accordion` | items, allowMultiple, variant (flush/card) |
+| `element:text` | content, variant (heading/subheading/body/caption), align |
+| `element:number` | object, aggregate (count/sum/avg/min/max), field, filter, format, prefix, suffix |
+| `element:button` | label, action (inline ActionDef), variant, size, icon, iconPosition, disabled |
+| `element:definition-list` | items, columns, inline |
+| `element:repeater` | object, titleField, fields, filter, sort, limit, emptyText, divided |
+
+`page:section`, `page:footer` and `page:sidebar` are left at zero inputs on
+purpose: their renderers render `children`/`body` and nothing else — like
+`element:divider`, they are genuinely prop-less containers, and inventing
+inputs for them would be the opposite falsehood.
+
+`aria` and `className` stay undeclared throughout, per the convention on
+`record:details`: escape hatches and styling pass-throughs, not authoring
+choices. `element:button`'s registration also documents the split against
+`action:button` — inline ActionDef vs a declared action referenced by name —
+so the two stop reading as duplicates.
+
+Declaration only; no renderer behavior changes. Curation (which of these join
+`PUBLIC_BLOCKS`) is a separate change.
