/**
 * EvidenceFormBody — the shared "citation + commentary" editor.
 *
 * One form drives both:
 *   - the *capture* flow (creating evidence from a fresh selection
 *     inside `InlineCaptureForm`), and
 *   - the *edit* flow (modifying an existing evidence card inside
 *     `EvidenceSidebar`).
 *
 * Keeping a single component means changes to the field layout, hint
 * placement, or save-button copy land in one file and apply to both
 * surfaces. Callers control the labels and any badge/helper text.
