/**
 * Regression tests for buildFilamentOptions (#1248).
 *
 * The original bug was precedence-based merging: cloud presets, when present,
 * fully replaced the local-presets branch and silently hid Local Profiles.
 *
 * The follow-up clarification: the spool form is printer-agnostic, so it must
 * show every per-printer / per-nozzle variant of a preset as its own entry —
 * unlike the AMS Slot modal which is per-printer and filters down to the
 * active printer model. Both surfaces should render the same set of presets
 * if you summed the AMS Slot's per-printer-filtered output across all
 * printers; the spool form just shows the union directly.
