// Standalone tests for reasampler::render_settings — no REAPER, no framework.
// Covers the three pure pieces behind the M7 capture family: the source-mode ->
// RENDER_SETTINGS bit mapping (wet-only), P_RAZOREDITS parsing -> ranges + union,
// and the capture-action taxonomy table (stable ids, coverage of every mode).
