VU needle (animated) - Synthetic wobble bounded by current volume runs only while state==='playing'. Two combined sines + jitter make it look like a real analog needle reacting to peaks. - Settles back to the static volume-mapped position when paused. Spectrum (real audio) - Now driven by the same frequencyData the visualizer canvas uses. Each visual bar averages a chunk of frequency bins. - Spans are now JS-injected (60 bars) instead of hardcoded so the bar count is no longer baked in. - Spectrum spans full width of the masthead column, height bumped to 56px for presence. - CSS animation pauses (sets via `body.audio-spectrum-live`) when JS is driving heights so the keyframes don't fight. - Synthetic CSS animation remains as the fallback when audio capture isn't available. Visualizer auto-enable - On first install with loopback support, visualizer is enabled so the spectrum is alive out of the box. Dynamic background - Lower max opacity (1 → 0.45 dark, 0.35 light) - sepia + saturate filter + hue-rotate keep it palette-aligned with the copper editorial tones instead of fighting them - mix-blend-mode screen (dark) / multiply (light) blends into the page background instead of overlaying Update + connection banners - Fully restyled: glassy card with copper hairline accent, mono uppercase text, copper hairline-border CTA buttons, minimal close button. Matches the rest of the editorial palette instead of the old solid-green-bar look.
