[lana-20]

The reference, quick start and guides regenerate from Mobium's main on every build, so they were already current. The hand-written examples were not. Since 2026-10-01, Mobium added the following, and none of it had an example:

• press: a TV remote's D-pad, select and media keys, and --gesture for back. The clients gained back.
• upload / download: --device-path, to send or fetch a file or folder at any path on the device. The clients gained push_path / pull_path.
• fill: sliders, by position.

Five scenarios, in every client

Page	Scenario	Recorded on an Android 15 emulator
press	mobium press dpad-down	pressed dpad-down — focus moved to homepage_container
press	mobium press back --gesture	swiped back from the left edge … still in the foreground
upload	mobium upload ./seed --device-path /sdcard/seed	a folder of 2 files, 8 bytes, each size read back
download	mobium download --device-path /sdcard/seed -o seed-copy	the same folder back, sizes checked
fill	mobium fill label=Volume 0.3	moved label=Volume to position 0.3 — it reads "3.0", was "5.0"

Each scenario is in canonical.json and translated into Python, JavaScript, Go, Java and .NET. Each page already had its picture, so these record output only.

Also

• capture.py --only now also takes one run's key (--only 'app_press[2]') as well as a tool. That way a new scenario is recorded without re-taking the pictures beside it.
• The JavaScript D-pad example depends on Clients and descriptions caught up: press's TV buttons in the JS types; type and fill are not Android-only (CHALLENGES 231, 232) mobium#119, already merged. That PR fixed the client's types to accept the D-pad. Checked against Mobium from before the fix, the example fails with the exact type error #119 fixed.

Checks

• Locally, against Mobium main (5f2e6f1):
  • extract: 71 tools, 85 commands.
  • check_examples: 104 scenarios and every Python, JavaScript, Go and Java snippet, 0 problems.
  • generate: 519 pages.
  • npm run build: succeeds.
• .NET: not installed on this machine. This PR's CI checks it.
