v1.35.0

### Fixed
- **Feedback backgrounds no longer change brightness with the frame rate.** The 14 effects
  that accumulate particles into a trail — Cascade, Tesla, Mycelium and others — settled at
  about half their intended brightness at 30 fps and double at 120. Measured on Cascade:
  47.7% spread across 30/60/120 fps, now 6%. Nothing moves at 60 fps.
- **Particle ribbon trails last the same time at any frame rate.** Cleave, Tide and Vessel
  measured their trails in frames, so a trail running 267 ms at 60 fps stretched to 533 ms
  at 30 and shrank to 133 ms at 120.
- **Panorama's graticule no longer brightens or smears with the frame rate.** Its centre and
  edge guides were drawn at a fixed strength per frame, and its echo drifted a fixed distance
  per frame, so the reference line the effect exists to provide got both stronger and wider
  the faster your machine ran. Brightness spread across 30/60/120 fps drops from 59% to 1%.
- **Ascend's horizon wake rises at the same speed on any machine.** The afterglow climbed a
  fixed distance every frame rather than every second, so it travelled twice as far per
  second at 120 fps as at 60. Brightness spread across 30/60/120 fps drops from 14% to 2%.
- **Diffusion blur is measured in seconds now**, so Protea's bodies, Sumi's ink and
  Polycephalum's network smooth at the same rate however fast the machine runs. Protea's
  brightness spread across 30/60/120 fps drops from 41% to 18%.

## Downloads

| Platform | File | Notes |
|----------|------|-------|
| **macOS** | `.dmg` | Universal binary (Apple Silicon + Intel) |
| **Linux x86_64** | `.tar.gz` | glibc 2.35+ (Ubuntu 22.04+, Debian 12+) |
| **Windows x64** | `.zip` | Windows 10+ |

## Getting started

**macOS**: Open the DMG, drag Fosfora.app to Applications (or run directly). Signed and notarized.

**Linux / Windows**: Extract, run `fosfora` from the extracted directory. The `assets/` folder must be next to the binary.

## Requirements

- **GPU**: Vulkan (Linux/Windows) or Metal (macOS)
- **Audio**: Built-in mic or line-in for audio-reactive visuals
- **NDI®** (optional): [NDI® SDK runtime](https://ndi.video) for network video output
- **Video playback** (optional): `ffmpeg` on PATH for media layers
