 * Figma-like comments e2e (collab-presence 0005): two tabs of the real React
 * app on the SAME schematic share the comments map in the per-file Y.Doc.
 * Flow: alice pins a comment via comment mode → bob sees the pin, opens the
 * thread, replies → alice sees the reply live → resolve → delete clears both.
 *
 * Uses eeschema (demo.kicad_sch — the comment bridge ships in the merged
 * kicad_editor bundle, so pcbnew/eeschema only; pl_editor has no pins).
 * The GAL dot is drawn by the wasm; the assertions here drive the DOM halves
 * (hit targets, composer, popover) which is what this layer owns.
