Use dt.timezone.utc so the declared >=3.10 support is real
`dt.UTC` is a 3.11+ alias, but crdt-sync declares requires-python = ">=3.10"
and the CI matrix tests 3.10 — so `crdt-sync tests` has been failing on the
3.10 leg since before this branch (commit 493db693 failed the same way).
It collected as `AttributeError: module 'datetime' has no attribute 'UTC'`.

This is not only a test problem: `_firebase_auth._utcnow()` is library code,
so on 3.10 every token-expiry check would have raised at runtime. The three
consumers (diet-guard, screen-locker, wake-alarm) all declare >=3.10 too, so
honouring the floor is the right direction rather than raising it.

`dt.UTC is dt.timezone.utc` evaluates to True — the same singleton under two
spellings — so this is a pure rename with no behaviour change.

Verified on a real pyenv 3.10.16 venv, not just the 3.14 dev interpreter:
239 passed.

utils

Shared libraries used across kuhyx's other projects. Each subdirectory is a formerly-standalone repo, folded in here with full commit history preserved (see each subdirectory's own git log for its pre-merge history).

crdt_sync_dart/

Dart/Flutter CRDT sync library (pub package name: crdt_sync, not published to pub.dev — consumed via a git dependency). Mirrors crdt-sync (below) module-for-module and test-for-test. Consumed by diet_guard's app, screen-locker's workout_app, wake_alarm's phone_app, and todo (whose notes are stored in the v0.2.0 LogStore).

Consume via:

dependencies:
  crdt_sync:
    git:
      url: https://github.com/kuhyx/utils
      ref: crdt_sync_dart-v0.2.0
      path: crdt_sync_dart

crdt-sync/

Python CRDT sync library (package: crdt_sync, not published to PyPI). Same design as crdt_sync_dart (HLC clocks, per-field LWW, sticky-delete tombstones). Consumed by diet-guard and screen-locker.

Consume via:

crdt-sync @ git+https://github.com/kuhyx/utils@crdt-sync-v0.2.0#subdirectory=crdt-sync

guard-lib/

Bash tamper-resistance primitives (guardctl: chattr + bind-mount + systemd watcher + pacman hooks). Not a package — installed by running guard-lib/install.sh as root, which copies files onto the system (/usr/local/bin, /usr/local/lib/guard-lib, systemd units, pacman hooks). Consumed by steam-backlog-enforcer (expects a guard-lib/install.sh sibling clone) and referenced by screen-locker.

gatelock/

Python lock-window + HMAC log-integrity backend (package: gatelock, not published to PyPI). Consumed via pip by screen-locker, diet-guard, and wake-alarm:

gatelock @ git+https://github.com/kuhyx/utils@gatelock-v0.1.0#subdirectory=gatelock

unified-design-system/

Not a package — the frozen design tokens (colors, spacing, type, radius, shadow policy) and per-stack (Flutter/web/Tkinter) implementation patterns that keep every one of kuhy's repos visually identical, plus annotated component references (components.html, button.html). Read unified-design-system/README.md and tokens.md before touching any theme/CSS/style file in any repo. The unified-design-system Claude Code skill is a thin pointer here, not a duplicate.
