PC Settings > Gameplay(page8/8), row5: PAUSE MUSIC ORIGINAL / REC ROOM.
Original is the default for old settings files. The toggle persists normally
and can change playback immediately while paused. Shared native font/panels,
gold focus border/arrow and centered labels are retained. The old Gameplay
R3 hint was removed to make room; Free Camera page7/8 has L3/R3 instructions.

The native PauseMusic controller plays the original Rec Room sequence5 in an
isolated host player255, retaining the original music keys. Background voices
are suspended independently of the original game's own paused flags; their
sequencer/sample state is not advanced or restarted. Normal menu effects keep
playing. New background voices started while paused inherit suspension. Resume,
setting Off, scene exit or stop-all removes the theme and releases suspension.
Stage and minigame pause hooks share this controller. No second SDAT/archive
instance or ROM bytes are compiled into this feature. Existing channel-fidelity
limitations are separate and remain open.

Verification:
- Native build,7 focused settings/camera/video tests and10 focused sound/input
  tests pass (overlapping tests,12 distinct CTests). Native-data audit passes.
- Local-SDAT probe --pause-music: confirms ordinary same-player starts would
  replace the original voice; isolated theme does not. Menu effects are audible
  while music is held. After128seconds of theme playback, stopping it preserves
  a separately applied retail pause flag. On resume,32768 PCM frames match the
  uninterrupted reference exactly. Zero engine errors; no device output.
- Exact final EXE, all muted and isolated, exit0/errors0/device nonzero0:
  Castle7200ticks: setting On/Off/On in pause, resume, another pause/resume;
  no active BGM exists in this fixture after title/file music stops, so retained
  background count0 is expected. Do not claim a castle BGM resume sample there.
  Battlefield4100ticks/240FPS setting: same transitions retain/restore one live
  music key each time, all three sessions balance and end cleanly.
  Wanted6500ticks: pause/settings/resume, retry and pause/return to Rec Room/back
  to title; both theme sessions stop without leaving a second theme playing.
  This is selected runtime coverage, not all minigames/courses or listening QA.

Includes the previous free-camera sensitivity/inversion/acceleration checkpoint;
its math/menu/reload checks were rebuilt and pass. Physical Nintendo Switch Pro
and broad listening accuracy remain unverified. Mixed scenes can still clip.
The full port, Lakitu cloud timbre, flower warp and minimap-side counters remain
unfinished. Full native executable contains local ROM data and stays private.
