Spectrum
- Logarithmic frequency-to-bar mapping (squared time so bins
stretch toward the highs). Per-bar high-end gain ramps from
1.0x at the lowest bar to 3.0x at the highest, so the right
half of the spectrum no longer reads as dead air.
- Floor bumped from 6% to 12% so silent bars stay visible.
- Skip bin 0 (DC + sub-rumble) which was overwhelming the lows.
- Use peak (not average) within each band — punchier visual.
- Container height 56→64, gradient now copper-lo → copper →
copper-hi for more visible top tips. min-width: 0 / box-sizing
border-box ensures the row truly claims the full grid column.
- Backend FFT path is unchanged: WS audio_data → setFrequencyData
→ renderVisualizerFrame → updateEditorialSpectrum. No
client-side analyzer added.
Album art (vinyl label)
- Deeper sepia (0.35→0.6) and lower saturate (0.85→0.7) so
vibrant covers blend into the copper grooves.
- Soft radial mask: outer ~22% of the disc fades toward the
vinyl black so the album art dissolves into the surface
rather than terminating at a hard clip edge.
- Hover state pulls the fade inward and eases sepia back so
the user can still see the real cover at near-natural color.
- Glow tint matches the new sepia depth.
