Marcos Paulo d4ebd50460 chore: debrand ArtCraft and Discord references 
Remove the Discord header button, Help menu and macOS app-menu links, About and Home
website links, brand assets and wordmark; rewrite docs, packaging URLs and catalogs.
Add .debrand rules and the craft-skills submodule (debrand skill) to keep upstream
syncs clean.

@@ -16,7 +16,6 @@ FilmCraft is a clean-room, open-source, pure-Rust non-linear video editor target
- **Pure Rust** in the product. OS media APIs only via Rust bindings in `crates/platform` (hardware decoding; the one crate allowed `unsafe`, see `AGENTS.md` §0.3 and `docs/adr/0001-platform-ffi.md`), optional, behind traits, with our decoders as the fallback.
- **Layering** ([`docs/architecture.md`](docs/architecture.md) §1, enforced by `cargo xtask layers`): nothing below L5 depends on egui/eframe/winit/rfd/cpal. L0 codec/container crates depend only on `filmcraft-bitstream`.
- **Exact time:** all time is `filmcraft_time::Tick` (254 016 000 000/s). Never use f64 seconds for edit math.
- **Time goes through `chrono`** (workspace dependency). Never hand-roll UTC/calendar conversion (days-to-date algorithms, leap-year math); a crate owns only its output format string. The one exception is range extension: past the years chrono can represent, shift the date by whole 400-year Gregorian cycles (146,097 days, after which the calendar repeats), let chrono compute the month and day, and add the cycles back to the year (splitting seconds into hours, minutes and seconds is plain arithmetic).
- **Everything is a command** (`crates/engine`): id, label, menu path, shortcut, params, enabled(), run(). UI, CLI, control channel and MCP all dispatch by id.
- **Everything is agent-drivable:** every interactive widget registers an automation id; UI state is serde so the control channel can read/set it.
- **Quality gates** before every commit: `cargo fmt --check`, `cargo clippy --workspace --all-targets -- -D warnings`, `cargo test --workspace`, `cargo xtask layers`, `cargo xtask assets`, `cargo xtask wasm` (checks L0–L4 crates). `cargo xtask ci` runs them all.

- **Every trim.** Ripple, roll, slip, slide, rate stretch and razor tools. Trim mode selects edit points as ripple, roll or trim, nudges them a frame at a time (`⌥←` `⌥→`, ×5 with `⇧`), toggles the trim type with `⌃T` and extends them to the playhead with `E`. `Q` and `W` ripple-trim to the playhead. The **Trim Monitor** shows both sides of the edit, and **dynamic trimming** trims live while it plays: `L` forward, `J` back, `K` to stop and commit as one undo step.
- **Exact time.** Every edit is computed on integer ticks: 254,016,000,000 per second, which divides evenly by every common frame rate and sample rate. 23.976, 29.97 drop-frame and 59.94 are exact, not approximate.
- **The details pros rely on.** Markers with colours, names and durations; export sequence review notes with **Markers ▸ Export Markers as CSV…**; add edit (`⌘K`) on one or all tracks; nesting; copy, paste and paste insert; ripple delete and close gap; snapping; unlimited undo with a History panel.

Every menu item, button, slider and drag in FilmCraft is a **command** with an id, typed parameters and an enabled state. There are more than 650 engine commands (`filmcraft-cli commands` lists them), with more commands continuously added. The UI, the CLI, a JSON control channel and an **MCP server** all dispatch the same commands, so Claude or any agent can cut, trim, grade, mix and export exactly the way a person does. The UI can also be driven at the level of mouse and keyboard: every widget has an automation id, and agents can click, drag, type and take screenshots.

FilmCraft is young and moving fast. Editing, trimming, multicam, colour, keyframes, effects, titles, captions, mixing, codecs and export work today.
FilmCraft is in **alpha**. We track two numbers ([docs/target-app-parity.md](docs/target-app-parity.md), re-measured 2026-10-10):
FilmCraft is in **alpha**. We track two numbers ([docs/target-app-parity.md](docs/target-app-parity.md), re-measured 2026-10-10 against Premiere Pro 26.5.2):
- **Feature breadth: ~86%.** Professional NLE menu items, effects, transitions, panels and formats that exist in FilmCraft (menus 92% and effects 100% measured).
- **Ready for real work: ~56%.** Our honest estimate of how close FilmCraft is to handling full production work on real projects.
- **Feature breadth: ~86%.** Premiere Pro's menu items, effects, transitions, panels and formats that exist in FilmCraft (menus 92% and effects 100% measured).
- **Ready for real work: ~56%.** Our honest estimate of how close FilmCraft is to replacing Premiere on real projects.
The biggest gaps today:
- **Speed on big footage.** Hardware decoding works on macOS and Windows, and for H.264 and HEVC on Linux (VA-API, or NVDEC with NVIDIA's driver; VP9 and AV1 decode in software there). Blend modes and the most common effects run on the GPU, but color grading, keys and export rendering still run on the CPU; H.264 encoding can use the hardware encoder on macOS and on Windows and Linux with an NVIDIA GPU (opt-in, Export ▸ Hardware encoding), and H.265 export is hardware-only on both (HDR sequences export Main 10 PQ / HLG with NVENC; VideoToolbox writes 8-bit SDR) ([#30](https://github.com/storytold/filmcraft/issues/30)).
- **Native `.prproj` project import.** `.prproj` files can't be opened yet; bring sequences over as FCP7 XML, AAF or OTIO.
- **Speed on big footage.** Hardware decoding works on macOS and Windows, and for H.264 and HEVC on Linux (VA-API, or NVDEC with NVIDIA's driver; VP9 and AV1 decode in software there). Blend modes and the most common effects run on the GPU, but Lumetri, keys and export rendering still run on the CPU; H.264 encoding can use the hardware encoder on macOS and on Windows and Linux with an NVIDIA GPU (opt-in, Export ▸ Hardware encoding), and H.265 export is hardware-only on both (HDR sequences export Main 10 PQ / HLG with NVENC; VideoToolbox writes 8-bit SDR) ([#30](https://github.com/storytold/filmcraft/issues/30)).
- **Premiere projects.** `.prproj` files can't be opened yet; bring sequences over as FCP7 XML, AAF or OTIO.
- **No plugins.** No VST3 / Audio Units or OpenFX hosting.
- **Delivery codecs.** H.264 is our only software delivery-codec export; H.265 exports only through a hardware encoder (NVIDIA on Windows: Main 8-bit SDR and Main 10 HDR PQ / HLG; VideoToolbox on macOS: 8-bit Main, SDR); no AV1 export yet.
- **Real-world media and platforms.** Our decoders are bit-exact on conformance streams, but camera and phone files in the wild are less tested. Windows and Linux get far less testing than macOS.
- **AI features.** Few so far; speech to text is optional and off by default.

An explicit `gl` override can bring the driver crash back on affected systems. The macOS, Linux

A PC whose GPUs were installed from different driver packages of one vendor (a laptop with an
integrated and a discrete AMD GPU, for example) can list one GPU twice, once through each installed
version of the Vulkan driver, and a window drawn through the stale one crashes inside the driver
(`amdvlk64.dll`, exit code `0xc0000005`). FilmCraft draws with the newer one and says so in

- **2026-10-12:** Transform's motion-blur shutter on adjustment layers uses the sequence frame rate instead of 24 fps, so a 360° shutter in a 60 fps sequence spans one frame, not 2.5 (#1088)
- **2026-10-10 (changed media):** Settings ▸ Media ▸ Automatically refresh growing files works: media files that change on disk while the project is open (a recording still being written, a render written over the file a clip uses) are read again every *Refresh growing files every* seconds and as soon as the window comes back to the front: the new length, picture and identity, without an undo step (`media.refreshChanged`, `media_watch`).
- **2026-10-10 (re-measure):** full parity re-measure against Premiere Pro 26.5.2: menu label diff 338 / 366 (92%), installed bundle listings (10 UI languages, exporter and codec frameworks), 188 open issues.

//! Graphics start-up: the wgpu backends and adapter the window is created with, and the fallback
//! when a start fails (docs/gaps.md G4, #820).
//!
//! A graphics driver can crash inside wgpu instance or device creation (Intel's Vulkan driver
//! `igvk64.dll`, #512 #413; AMD's OpenGL driver `atio6axx.dll`, #477), where no Rust error
//! handling runs, so every launch died the same way until the user set `WGPU_BACKEND` by hand.
//!
//! # The adapter
//! In the default mode on Windows the adapter is wgpu's own choice, except for a GPU that Vulkan
//! lists through two installed versions of one driver: there the newer one draws, because a
//! window drawn through the stale one dies inside the driver (`amdvlk64.dll`; see
//! `filmcraft_gpu::adapter`). That case is avoided up front instead of left to the fallback
//! below, which would end in DirectX 12 only.
//!
//! # When a start counts as failed
//! The data folder keeps the mode to start with and the failed starts in a row in it
//! ([`STATE_FILE`]). Each start also leaves its own attempt file (`graphics-start/<pid>-<n>.json`,
//! so concurrent launches never write the same file) that is removed once the window has painted
//! two frames, when the process ends normally, or [`DEATH_WINDOW`] after launch, whatever happened
//! by then. An attempt file found by a later launch therefore means a process that died within
//! [`DEATH_WINDOW`] of its start without painting: a driver crash, typically. A start that hangs,
//! or is force-quit or crashes later, is not counted; neither is another instance that is still
//! starting (its attempt is younger than [`DEATH_WINDOW`] and is left alone). After
//! [`FAILURES_TO_MOVE_ON`] such failures in a row in the same mode, the launch moves on to the next
//! [`Mode`] of the platform's [`LADDER`] and keeps it; a start that paints resets the count. A
//! start-up error that wgpu does report (no adapter, device creation failed) moves on at once,
//! within the same process.
//!
//! # Getting back
//! A fallback mode shows a notice with a reset button in the window (`graphics.notice.reset`,
//! [`GraphicsStart::reset_to_default`]); `--graphics default` does the same from the command
//! line, and `--graphics dx12|software` picks a mode by hand. An explicit `WGPU_BACKEND` leaves
//! the saved state alone: the user is in charge.
//!
//! All files are written beside and renamed into place, so a reader never sees half a file; two
//! instances updating [`STATE_FILE`] at the same moment can lose one update (a failure counted
//! once less, a confirmation repeated by the next start), never corrupt it.
