v2.0.0

Fosfora has a new interface. It opens in three workspaces, Perform, Build and Setup, with the output as a live preview beside them instead of behind two narrow side panels.

### Added
- **The workspace layout, now the default for new and upgrading installs.** The old two-panel layout is *Classic layout* under Setup ▸ General for this release, and goes away in v2.1.
- **Build shows the layer stack as pictures**: each row is the stack blended up to that layer, and Master on top is the final output. The inspector beside it shows whatever you select, with every section the effect brings, and the chain editor opens there too.
- **A catalog of effect pictures** along the bottom of Build, in families, with search and favorites. Hover a picture to see it move; click it to load it, or drag it onto the stack to replace a layer's effect or add a layer.
- **Scenes are a strip of cues** in the drawer, in Build and Perform. Each cue shows its preset's picture, transitions sit between them and the playhead runs along the strip.
- **Setup is a list of pages**, each device saying its state in words beside an On/Off switch. NDI, the virtual camera, Spout, Syphon and Ableton Link are all there, and Triggers can map Timeline, Tempo ÷2, Tempo ×2 and Tap tempo.
- **Send the output to a second display** in a borderless window with no interface on it. Pick the display under the output preview; Esc closes it.
- **Every control has a Bind** that opens Bindings with that control already picked, and a bound control names its source on its row (◀ Kick).
- **Four guided tours**: First run, which starts by itself once, then Bindings, Chains, and Layers and blending, from the Tours menu or Setup ▸ Tutorials.
- **Interface scale** from 80 to 200 % under Setup ▸ Appearance, or Ctrl + and Ctrl −. The output is untouched.
- **Themes Light, Gray, Black, and Blue and orange**, plus custom themes: *Save a copy to edit* writes fifteen named colors to a file, and Appearance lists any that fail contrast.

### Changed
- **No state is shown by color alone**, and no text is smaller than 12 px at 100 % scale. Status lights have a shape per state, and selections differ by fill, outline or words.
- **Midnight, Ember, Neon and High Contrast are retired.** A saved choice moves to the nearest new theme.
- **The chain editor opens with C** (for chain) instead of G.
- **Post-processing belongs to the preset**: selecting a layer no longer changes it. Master can reset to any effect's recommended look, *Previous settings* undoes a reset, and editing it marks the preset as changed.
- **The app opens with an empty Layer 1 over the F**, and Clear stack and a new preset return to that. An empty layer is see-through instead of a dark gradient.
- **The launch effect is called Fosfora and traces an F.** Presets and bindings that name it Phosphor still load it, and new setups record to a Fosfora folder.
- **Bindings**: the *Effect* tab is now *Preset*, layers are numbered from 1, the window is solid, and an open card no longer cuts off its name, source and target.

### Fixed
- **Adding a video layer no longer freezes the app** for ~15 s while it decodes; decoding runs in the background with a progress bar and a Cancel button.
- **Kaleidoscope no longer draws a seam** from the center while it turns: *segments* steps in whole numbers. A trama effect can mark such a parameter `"integers"` in its manifest.
- Deleting a scene no longer closes the one you were editing, and a long scene name in a non-Latin script no longer crashes the app.
- Launching no longer logs a "missing field `layers`" warning for every preset with saved bindings.
- A section opens or closes from a click anywhere on its title bar, not only its arrow.
