 * The composer: role="dialog", focus-trapped, anchored near the pin (flipping to
 * stay in the viewport). Textarea (required, max 2000, live counter), optional
 * name input, Submit/Cancel, spinner, success/failure states, copy-to-clipboard
 * on failure, and the branding footer. Esc dismisses the composer but KEEPS the
 * typed draft (only Cancel discards it); a second Esc (handled by the overlay)
 * leaves comment mode. Cmd/Ctrl+Enter submits. Focus returns on close.
 * While the composer is untouched, clicking elsewhere on the page abandons the
 * pending pin and re-pins at the new spot (see overlay.pick / abandonClean).
