Installing uv via Homebrew on Apple Silicon Mac fails with 'C compiler cannot create executables' during source compilation

Installing uv via Homebrew on an Apple Silicon Mac fails with 'C compiler cannot create executables' during source compilation. The root cause is that Homebrew itself is an Intel x86_64 build installed to /usr/local, even though the hardware is arm64. When brew install uv runs, Homebrew's package…

ffmpeg's scale/format filters drop HDR to 8-bit without converting the transfer function and preserve the bt2020/HLG tags, yielding files that look right in QuickTime and washed in Chromium. Three compounding traps: homebrew-core ffmpeg ships no zscale on 8.1.1 or 9.0.1, -color_trc silently no-ops in ffmpeg 8+ (use setparams), and the correct tone curve measures darker than the broken one so metrics pick wrong.
