v1.0.12

• New (#4): opt-in "Normalize loudness across stations" toggle, off by default. Evens out real volume differences between stations/streams (ffmpeg dynaudnorm). Takes effect on the next Start or station switch, not live - some CPU cost, so it's off unless you turn it on.
• Fix: the "unsaved changes" banner was incorrectly appearing when moving the volume slider, even though it now auto-saves (v1.0.10). The slider no longer trips that banner; other fields are unaffected.

This release completes issue #4, reported by @bobreese.
