Release v1.15.0 · kevinraymond/fosfora

New effect: Panorama — the stereo field as a picture — the screen becomes a map of the mix: horizontal is where a sound sits between your speakers, vertical is its pitch. A centred kick anchors the bottom while hats and reverb tails fan out to the edges, the cloud bends left and right as the image moves, and a mono mix collapses it to a single column. Nothing else in the app shows you the stereo image.
New effect: Ascend — a horizon that tracks brightness, not volume — cymbal swells lift the field skyward and sub-heavy passages sink it, so it keeps moving through a passage that holds a steady level. A pure tone draws it taut; noise inflates it into drifting haze. Built to layer underneath another effect as a ground plane.
Per-band pan — seven new audio sources for where each frequency sits in the stereo image — the existing pan collapses the whole mix to one number, so a centred kick under wide hi-hats read the same as a mono track. Each of the seven bands now reports its own position, bindable from the matrix and emitted on /phosphor/audio/band_pan/*. A band carrying no energy reads centred rather than drifting. Costs one extra FFT per hop, since both channels come out of a single transform.

Shader ABI: particle uniforms 896 → 944 bytes, effect uniforms 400 → 432 bytes — both gain band_pan (7 bands + 1 pad, read with band_pan(i)), and particle sims additionally gain pan, stereo_width and stereo_corr, which fragment shaders have had since v1.9.0 but no particle sim could reach. Both blocks are appended, so every existing field keeps its offset: custom shaders need recompiling, not editing.
