Added

• Activity export (FIT / TCX). Export any past ride from its overview as a
  FIT or TCX file and hand it to the OS share sheet - send it to Strava, Garmin
  Connect, intervals.icu, TrainingPeaks, or save it anywhere. A small sheet lets
  you pick the format. Both encoders are pure-Kotlin in the shared module (no
  third-party libraries), and the whole flow is offline - nothing leaves the
  device except through the app you choose.
• Tablet & large-screen UI. The app now adapts to tablets and unfolded
  foldables:
  • A side navigation rail at wide widths (the bottom bar stays on phones).
  • A multi-column workout list instead of stretched full-width cards.
  • A reworked ride HUD with much larger power / cadence / heart-rate
    readouts, a taller workout-profile timeline, and a live stats strip showing
    elapsed time, average power, and interval progress, all tinted to the
    current power zone.

Changed

• Backup & sync is now wipe-safe. If the app's local data looks accidentally
  reset (after a reinstall, cleared storage, or a bad migration), sync now
  pauses instead of overwriting your backup, and surfaces a clear choice:
  Restore from backup (pull your rides and settings back onto the device) or
  keep the device's data. Each backup file is also kept as a recoverable .prev
  copy before being overwritten. Automatic and manual syncs both respect the
  pause until you resolve it.

Project / distribution

• The app is now distributable via Obtainium,
  which tracks signed APKs from the Codeberg releases for automatic updates.
  Install links / badge added to the README and the indoorbike.app home page.
• New editor URL workout API: third-party tools can open the in-browser
  workout editor with a workout preloaded via plain URL parameters. Human docs
  at indoorbike.app/api, machine spec at
  indoorbike.app/editor/llms.txt, plus optional "Open in Indoor Bike" badges.
• The editor now also loads workouts immediately with a non-blocking Undo
  instead of a confirmation dialog.

Notes

• versionCode 2, signed with the project's release key.
• Indoor rides carry no GPS, so GPX export is intentionally not offered - FIT and
  TCX both express time, power, heart rate, and cadence without a position track
  and are accepted by the major training platforms.

[1.0] (1)

• Initial pre-release: BLE FTMS smart-trainer control, ERG-mode power-zone
  workouts, plain-text JSON workouts with an in-browser editor, on-device
  progression (streaks, levels, badges, time-in-zone), FIT export with optional
  Intervals.icu sync, and folder-based cross-device backup. F-Droid posture
  throughout (no Google Play Services, no analytics, no proprietary blobs).

Open your Training Hub → Activity Feed → find the treadmill session → edit distance or elevation manually. Save. Your next prediction picks it up.

The journal is where we point. Short posts, mostly links out, sometimes our own notes. No essays for the sake of them. If we don't have anything to say beyond "read this," we'll just say "read this."
