Team PTO Calendar.

Build a team PTO calendar for Waypoint Labs, a 14-person remote software team, so anyone can see who is out when, what balance everyone has left, and where too many teammates overlap. Layout. The hero is a month grid calendar with a previous and next month switcher, defaulting to the current month. Each day cell lists the people out that day as small chips colored by leave type: teal for vacation, amber for sick, neutral gray for company holidays that apply to everyone. Weekends render muted. Above the calendar, four stat cards: Out today (2), Out this week (4), Requests in the next 30 days (9), and Coverage warnings (1). When two or more people from the same team are out in the same week, show a warning banner above the calendar naming the team and the week, and outline those chips in red. To the right of the calendar, stacking below on narrow screens, a Balances panel lists all 14 people with team badge, annual allowance of 15 days, days used, days remaining, and a thin progress bar, sorted by fewest days remaining. Include a team filter above the calendar that narrows both the grid and the balances panel. Data. Seed 14 people across four teams: Support (4), Engineering (6), Design (2), Ops (2), with realistic names. Seed about 45 leave entries spread over a 3-month window covering last month, this month, and next month, mostly 1 to 5 day vacations plus scattered single sick days, and two company holidays. Seed the entries so two people are out today and four are out at some point this week. Plant two stories: three of the four Support people overlap for the same week about three weeks from now, which must trigger the red coverage warning, and Priya Nair on Support is down to 1 day remaining after a two-week trip last month, highlighted red in the balances panel. Keep every other team to at most one person out in any given week so the Support overlap is the only warning. Behavior. Balances are computed from entries, never typed in: used equals the sum of weekday leave days logged, remaining equals allowance minus used, and holidays do not draw down balances. A Request time off button opens a dialog capturing person, leave type, start date, end date, and an optional note, and the new entry appears on the grid immediately. Writes are member-only, so the calendar, warnings, and balances must all read perfectly for an anonymous visitor. Visual identity: use a teal accent for primary actions, vacation chips, active states, and the selected month, on a calm light neutral base so the amber and red warning states stand out.
