facett-markdown/tests/matrix.rs

//! **The functional matrix cell for facett-markdown** — the pane emitted NO
//! testmatrix row of either aspect before this file (see
//! `.nornir/docs/test-matrix-inventory-history.md`, "~10 panes emit no cell").
//!
//! ONE call: the shared generic-`Facet` probe in `facett_core::harness` renders
//! the pane headlessly, drives the JSON robot seam, and
//! `facett_core::testmatrix::probe_and_emit` turns the result into the
//! `headless_render` + `responds_to_input` rows. No bespoke harness (L5).
