irene afe397da3f refactor: draw the src/scripts boundary, drop dead files
Make each directory answerable by path alone: src/ is what the Remotion build
compiles, scripts/ is what you run by hand.

Removed:
- `ffmpeg.sh` — never worked; every parameter was assigned `$1`, so bake/bypass
  were broken from the start. Superseded by `scripts/ffmpeg_tools.py bake|still`.
- `src/lrc2srt.ts` — the TypeScript port; `scripts/lrc2srt.py` is the script that
  was actually maintained, and it now handles the multi-timestamp cases the TS
  version did.
- `scripts/bom-gen.ts` — superseded by `scripts/bom_gen.py`.
- `scripts/ffmpegusage.txt` — legacy command notebook. Every recipe in it is now
  reproduced by `ffmpeg_tools.py`, including the `-map 0:v:0 -map 1:a:0 -c:v copy`
  mux and the FLAC `-compression_level 12` case, so it has no unique content left.

Also drops the `bom-gen` alias from the dispatcher (dash-case was TypeScript
naming) and documents the boundary in README.md and REMOTION-QUICKSTART.md.

`npm run lint` (eslint src && tsc) passes with src/ reduced to Remotion input.

# Video-related files for NCMR songs
This repo houses the code-like files for NCMR music videos. Binary assets live elsewhere.
## Structure
> **Repo state: workspace under construction.** `master` is *not* locked in yet —
> it is still being assembled as the shared template. Until it is locked, any
> branching strategy is fine and template/tooling work can land on `master`
> directly. The branch conventions below describe the intended end state, not a
> rule currently in force.
### `master` branch — shared template
This branch holds the common scaffolding:
- **Remotion project** — entry point, root component, and a placeholder composition
- **`scripts/`** — Python toolchain (stdlib only) for subtitles, ffmpeg and asset manifests
- **Build config** — TypeScript, ESLint, Prettier, Remotion studio
### `src/` vs `scripts/`
Two directories, two jobs:
- **`src/`** — Remotion input only. Everything here is compiled by `tsc`/Remotion
and linted by `npm run lint`.
- **`scripts/`** — operator tooling. Python, standard library only, run directly
(`python3 scripts/tools.py --help`). Nothing here is part of the Remotion build.
Keep the boundary sharp: anything the video build compiles belongs in `src/`, and
anything you run by hand belongs in `scripts/`.
### Song branches
For each song, create a branch `<song-name>/master` (and optionally feature branches
like `<song-name>/synced-lyrics-remotion`):
```
git checkout -b <song-name>/master
```
Copy the shared template into the song branch, then add song-specific files:
```
mkdir -p <song-name>
# Place your song-specific compositions, assets manifests, etc.
```
Once `master` is locked in it remains protected and mostly immutable. Until then,
song branches are a rehearsal for that end state, not a requirement.
## Guideline
### Git-ignored (not tracked here)
- Binary input assets (audio, images, fonts, material video clips)
- Video output (`out/`, rendered files)
For untracked input assets, a **bill of materials** listing everything and explaining
what each file is will be mandatory. Keep it as `BOM.md` alongside your song assets.
### Branching
- `master` — minimal template (protected once locked in)
- `<song>/master` — song-specific work
- `<song>/<feature>` — parallel features for a song
Once `master` is locked, this repo's branching rules supersede any generic git
operation conventions. Before that point, use whatever is convenient.
