Layout: isolated_card centered in the viewport (light theme, comfortable spacing, default scale).
The card title reads “Project calendar”. Inside the card is an Ant Design Calendar component showing February 2026 by default.
The calendar header includes month and year controls (month selector + year selector) and left/right navigation arrows.
No date is selected initially; only the standard hover/active styling appears when interacting.
Below the calendar there is a small readout line labeled “Selected date:” which updates live to an ISO date (YYYY-MM-DD) when a day cell is selected.
There are no other interactive elements on the page (no clutter/distractors).

Layout: isolated_card centered (light theme, comfortable spacing, default scale).
The card contains a single Ant Design Calendar. It initially renders February 2026.
The header shows the current month/year and provides controls to change them (month dropdown, year dropdown, and previous/next navigation arrows).
No day is pre-selected and selecting a day is allowed, but it is not required for this task.
A small, non-editable label above the calendar reads “Viewing:” and mirrors the calendar’s current visible month in the format YYYY-MM.
No other interactive elements are present (clutter: none).

The card contains a single Ant Design Calendar set to February 2026.
Above the calendar header is a small “Target” chip: a blue pill showing the text “Target: 2026-02-18 (Wed)”.
Inside the calendar grid, the target day cell (February 18) also shows a small blue dot in the corner (rendered via dateCellRender), matching the chip color.
No date is selected initially. A “Selected date:” readout below the calendar updates live when you select a day.

The page shows an “Event details” form with several non-required fields (Title text input, Location text input, a non-functional “Timezone” dropdown).
Below these fields is a labeled section “Event date” containing a single embedded Ant Design Calendar (not a popover).
The calendar initially displays February 2026 and has no selected date.
The calendar header includes month/year selectors; changing month/year updates the grid immediately.
Beneath the calendar is a compact readout “Event date:” which mirrors the selected date in YYYY-MM-DD when a day is selected.
Distractors: the form fields are clickable/focusable but do not affect task success; only the calendar selection matters.

Layout: settings_panel (dark theme, comfortable spacing, default scale) centered in the viewport.
The panel section is titled “Maintenance window” and contains one embedded Ant Design Calendar labeled “Maintenance date”.
The calendar initially shows February 2026 with no committed selection.
Interaction is two-phase:
1) Clicking a day sets a “Pending” highlight on the calendar (visual selection state).
2) The choice is only committed when the user clicks the primary button labeled “Apply” in the panel footer.
The panel footer contains two buttons: “Cancel” (secondary) and “Apply” (primary). Clicking Cancel reverts any pending selection back to the last committed value (initially none).
A readout line labeled “Confirmed date:” displays the committed ISO date (YYYY-MM-DD) and updates only after Apply is pressed.
No other interactive controls affect success (clutter is limited to the settings panel chrome).

All three calendars start on February 2027 and have no committed selection.
Interaction is staged per team: clicking a day sets a pending selection highlight, but the team’s committed value updates only when the global footer button “Apply changes” is clicked.
The footer contains two buttons: “Discard” and “Apply changes”.
