v1.2.7

1.2.7 - 2026-11-01

Wording, not behaviour: the demo is the starter pack now. Everything the
add-in, the zip, the repository and the site call it uses one name, because
"demo" was doing three jobs at once - a demo of the software, throwaway sample
data, and the files a new install needs to have something to read.

• Every user-facing mention says starter pack: the README section, the
  downloads page card, docs/TUTORIAL.md, docs/STATUS.md, dist/README.md,
  the hardware checklist and the in-app comments. No screen inside the add-in
  said "demo", so no tour script changed its content; step 99 is still the
  first-run screenshot and the image is now 99_starterpack_seeded.png.
• The names on disk follow: demo/ is starterpack/,
  Bench-demo-<version>.zip is Bench-starterpack-<version>.zip,
  tools/gen_demo.py is tools/gen_starterpack.py,
  tools/make_demo_zip.py is tools/make_starterpack_zip.py, and the make
  targets are starterpack-gen, starterpack-check, starterpack-zip and
  starterpack-zip-check. So is the code: src/platform/starter.{h,c}
  (starter_install()), src/apps/starter_data.{h,c} (starter_files[],
  starter_file_count), and tests/test_starter_data.c,
  tests/test_starter_files.c, tools/test_starterpack.py.
• The wasm build follows too: the file the browser simulator seeds its
  in-memory filesystem with is starterpack.json, and the worker's message key
  is starterpack.
• What did not change: the ten files, their text, the destination folders
  (Bench/notes, Bench/cards, Bench/study, Bench/formulas), the rule that
  only missing files are written, the ASCII-only check and the size budget. The
  cards gained a few bytes because their own first line said "sample content for
  the demo folder" and now says "starter pack folder" - 17 877 B becomes
  17 901 B, and the zip 10 479 B becomes 10 495 B. Unverified on device.
• 1.2.6 keeps its own names: that release carries Bench-1.2.6.g3a and
  Bench-demo-1.2.6.zip, and its entry below still says demo, because that is
  what it shipped. From this version on, the file to download is
  Bench-starterpack-1.2.7.zip.
• two things the rename broke, both fixed here: the wasm build looked for a
  directory called starter pack (a path hit by the rename), found none, and
  wrote a zero-file seed - the browser simulator would have booted with an empty
  card; it now fails the build rather than ship an empty seed. And
  BENCH_NO_STARTERPACK= counted as "set", because the tour passes an empty
  value when it wants the seed kept, so the first-run screenshot showed an empty
  card. It reads the value now, and step 99 runs against a fresh filesystem.
