//! v3.6 c2 — dogfood usecase: search vehicle (insight main flow).
//!
//! Port reference: `insight/tools/maestro/flows/main/search-vehicle.yaml`.
//! Exercises the search modal: nav to Search tab → switch Vehicle
//! sub-tab → open search modal → fill query → submit → verify result
//! or empty-state header.
//!
//! # Why this dogfood
//!
//! Second business surface for the v3.6 c1 chunked-fill landing. c1's
//! Merlin chat verification stayed on a single chat input; this flow
//! drives chunked fill through a totally different React subtree (the
//! search modal, opened by `btn-search-open`, scoped to a Vehicle tab
//! result list). If the c1 fix is real and not modal-specific, fill
//! "ABC123" (6 chars) commits intact here too.
//!
//! Also exercises:
//!
//! - bottom-tab Search nav via `go_to_search` (repeat-while-not-visible
//!   `People|Vehicle`, mirroring the maestro subflow)
//! - segmented sub-tab tap inside the Search screen (`tap("Vehicle")`)
//! - modal id ladder: `btn-search-open` / `input-search` /
//!   `btn-search-submit` — three consecutive c2 host-resolve fallback
//!   calls inside an overlay modal, also exercising c1 topmost-modal
//!   filter when the modal opens
//!
//! # Reversibility
//!
//! Pure read — the search query is local + transient. No backend
//! mutation. Closing the modal returns to the Search screen, which
//! sits behind a bottom tab anyway.
