_ui_widgets.py's _button() always set fg=self._colors.fg (near-white)
regardless of bg, so any accent/success/warning/danger-filled button
under-contrasted (measured 2.2-3.6:1 vs the 4.5:1 floor). Added
_fg_for(bg) so fg is derived from bg instead of hardcoded -- fixes every
current _button() call site structurally, not per-instance. Found and
fixed 2 more standalone instances of the same bug outside the shared
helper (_window_setup.py's demo-close button, _heat_skip.py's heat-skip
button).
Bumps gatelock to the released v0.1.1 carrying the same on_fill token
plus the warm palette rework. Regenerated workout_app's launcher icon
assets to match.
Verified: gatelock 50/50 + screen_locker 859/859 tests, both 100%
coverage; pre-commit (incl. pylint against the real v0.1.1 install) green.
ScreenLocker now composes gatelock.GateRoot + gatelock.LockWindow for the
actual lock window instead of the inline WindowSetupMixin mechanics; the
verify/relaxed-day auxiliary windows (never the lock itself) stay as
plain Tk windows. The hand-copied _log_integrity.py is deleted in favor
of gatelock.log_integrity (the canonical, non-duplicated module). This
is the second of three migrations (diet_guard done, wake_alarm next).
Two deliberate behavior changes, both confirmed:
- dependencies = [] (pure stdlib) now includes gatelock, a documented
departure from the prior zero-deps stance.
- production grab upgraded from single-attempt-then-local-fallback to
diet_guard's retry-forever (robust to e.g. a fullscreen game holding
the grab).
Net hardening as a side effect: run()/close() now go through gatelock's
signal-safe lifecycle, so SIGTERM/SIGINT restore VT switching on every
exit path -- previously only a clean close() did, leaving VT switching
disabled if the service was killed mid-lock.
