LockConfig's colours moved into a nested LockPalette record; every _COLORS.<colour> read follows. Nothing about the gate's behaviour changed. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01HHCbkJWXHjtTUaqvnHRAqA

"""``ttk`` theming for the gate's History tab, and its public surface.
|
|
|
|
Split across three modules to keep each under the repo's 250-line limit:
|
|
:mod:`._gatelock_calendar_types` holds the data bundles, constants and
|
|
palette, :mod:`._gatelock_calendar_widgets` builds the widgets, and this
|
|
module owns the ``ttk.Notebook`` theming.
|
|
|
|
Everything the tab's controller (:mod:`._gatelock_calendar`) needs is
|
|
re-exported here, because that module already imports all seven names from
|
|
this one. The ``ttk`` import is also load-bearing beyond theming: the test
|
|
suite patches ``_gatelock_calendar_ui.ttk`` with a fake, so this module must
|
|
keep binding ``ttk`` at module level.
