+`MultiSelect` and `Checkbox` read their `id`, `aria-invalid`, `aria-describedby`,
+`aria-required` and `disabled` from it, so don't set those by hand; an id
+the field already has wins. Any other control: pass `id` to FormField and
+the same id to the control. One FormField holds one control: a second
+field inside it (an "Add ref" box under a picker) needs its own `id`, or it
+takes the field's. Popovers reset the wiring (`FormFieldBoundary`), so a
+picker's search box is safe. There is one size: labels are `text-sm`
+everywhere, also in dense panels (Guardrails). `className` is layout only.

+
+A setting with a control on the right (a Switch, a short Input) is
+`<SettingRow label description htmlFor alignStart as after>{control}</SettingRow>`,
+grouped in `<SettingRows>`, which splits rows with `divide-border/50` and pads
+each 12px (none at the group's ends). The title is a `Label` for the control
+(`htmlFor` = the control's id), so every switch has a name and clicking the
+title toggles it; `as="h2" | "h3"` keeps a heading tag, and the control then
+needs its own `aria-label`. `alignStart` top-aligns the control for wrapping
+descriptions. `after` holds a field that belongs to the row, 8px under it
+(the agent form's limit Inputs). Inline "switch + label" pairs (a filter
+toggle) are not SettingRows.
+
+### Checkbox (`ui/checkbox.tsx`)
+
+`<Checkbox checked onCheckedChange>` (Radix), never `<input type="checkbox">`:
+native boxes take the OS accent and ignore dark mode. `size`: `default`
+(16px, option rows), `sm` (14px, table cells). Unchecked it is an
