Why

A user request: "Sometimes I go a bit deaf in my left ear, so I adjust the left side by -1 to compensate."

What changed since Beta 8.30

Change	Detail	Evidence
Settings → Sound → Balance	Left +10 dB … Center … Right +10 dB in 1 dB steps (`settings.balance`, -10..=10, negative = left louder, clamped on load). The louder side is reached by lowering the other side's samples at the live sink gain (`VolumeRamp::balance`), never by raising one, so it cannot clip; jack and Bluetooth alike, live while playing (an atomic like the volume, no reopen). The list opens on the current value	Reborn `b12a1ee`; `balance_lowers_only_the_other_side` (-1 dB: 10 000 → 8913 on the right), `balance_opens_on_the_current_side_and_sets_it`
Sound page layout	Six rows no longer fit: once the focus reaches Balance the first row scrolls away, as on Display, so the Output card stays on screen	previews 27, 29d, 29e

Device results

Check	Result
Install by OTA staging (owner's player)	sequence 9500 Acknowledged after a normal update restart
Settings → Sound → Balance, driven with button events over SSH	Sound page and Balance list as in the previews; Left +1 dB selected → `session.json` `"balance":-1`; playback 4 s with it on: playing, 0 xruns, 0 playback errors; set back to Center (`"balance":0`)
Listening check of the shift	not done by ear in this session

Open

The left/right shift was checked in host tests (sample values) and on the device as a setting, not by ear.
