📝 Walkthrough

Walkthrough

This PR expands the Aurora Drift theme with complete configuration support: settings schema, UI controls, multiple color palettes, frame-rate-independent audio reactivity using a smoothSignal helper, dynamic layer indices, performance-mode rendering adaptations, and optimized shadow rendering. The audio multiplier function now accepts settings to return reactivity-dependent scaling.

Changes

Aurora Drift Theme Configuration and Rendering Enhancements

Layer / File(s)	Summary
Settings schema and validation foundation settingsStore.js, settings.js	DEFAULT_SETTINGS.auroraDrift is populated with full configuration fields; VALID_AURORA_* constants enumerate allowed values; sanitizeAuroraDrift() validates each field against allowed values; THEMES_SCHEMA defines UI-driven option sets for dynamic dropdown generation.
UI and renderer initialization renderer.js	visualizerState.auroraDrift defaults now include all configuration fields; THEME_INFOS.auroraDrift context menu expands to selectable controls for style, intensity, height, glow, motion speed, palette, audio reactivity, softness, and layer density; getActiveAudioMultiplier passes current Aurora Drift settings to the audio multiplier function.
Aurora rendering core configuration themes/auroraDrift.js, renderer.js	Configuration resolution expands across style/intensity/height/glow/speed/audio/softness/layer-density branches into a derived cfg object containing activeLayersIndices and selected palette; PALETTES dictionary maps palette names to HSL stop arrays; performanceMode is plumbed through to cfg and passed into drawAuroraDrift.
Audio reactivity refactor with smoothSignal themes/auroraDrift.js	Audio state tracking replaces in-place smoothing math with reusable smoothSignal() helper for frame-rate-independent level following; bass surge detection, mid-range variance/expressiveness, and treble shimmer are computed from baseline and smoothed levels; pulses, mid noise, and treble effects scale by cfg.audioReactivityScale.
Color computation with palette selection themes/auroraDrift.js	getAuroraColor() is refactored to accept explicit palette parameter; each layer derives its color progression from the active palette instead of relying on a single global array.
Dynamic layer rendering with explicit indices themes/auroraDrift.js	Layer iteration loops over cfg.activeLayersIndices instead of fixed count; drawAuroraLayer() receives actualLayerIndex alongside visual index; layerPhaseOffset and amplitude calculations derive from actual indices and incorporate audioReactivityScale.
Per-layer color and opacity effects themes/auroraDrift.js	Ribbon base color is derived from cfg.palette; opacityMultiplier is clamped against cfg.opacityCap to preserve readability; visual effects scale by audioReactivityScale.
Filament and shadow rendering optimization themes/auroraDrift.js	Shadow rendering conditionally calls window.ParalineShared.applyOptimizedShadow() with fallback to ctx.shadowBlur/ctx.shadowColor and cfg.blurMultiplier; filament vertical segmentation and line count adapt to performanceMode; stroke width uses cfg.filamentWidthScale.
Turbulence and shockwave effects themes/auroraDrift.js	Fold/turbulence phase and amplitude incorporate actualLayerIndex and per-frame energyFlowOffset; shockwave displacement and treble vibration scale by both cfg.audioReactivityScale and cfg.intensity.
Crest highlights and audio multiplier signature themes/auroraDrift.js	Crest-highlight opacity is clamped against scaled cfg.opacityCap; exported getAuroraDriftAudioMultiplier() now accepts settings parameter and returns different multipliers based on settings.audioReactivity level (subtle/responsive/balanced).

Poem

🎨✨ A drift of colors, palettes dance with light,
Audio pulses shimmer, smooth and bright,
Layers flow with dynamic index grace,
Each aurora wave now finds its place,
Glowing softly—reactivity takes flight! 🌌🐰
