Replaces #12, which committed every generated render into the repo. Rebuilt on
a clean branch because merging the original would have written those blobs into
main's history permanently, even with a later commit deleting them.
What changed from #12:
- Keeps docs/DESIGN.md and assets/logo-mark.svg (1.4 kB of vector text).
- Drops ~23 MB of PNG/MP4. They live in the Figma file, which was already the
source of truth and is linked from the doc. stoke's .git is ~23 MB; those
assets would have doubled it, forever.
- Adds the missing "files" whitelist to package.json. There wasn't one, so
npm pack shipped the whole working directory: measured 23.7 MB with the
assets, and it was already shipping the test suite without them. Now 26.7 kB
across 7 files.
The packaging bug is pre-existing and independent of the design work; the
oversized PR is just what made it visible.
61/61 tests pass; `stoke --version` → 1.3.0.
