[OpenSpec] [planix] task-due-date-warning

[WilcoLouwerse]

Add visual warning badges to task cards on the kanban board, indicating when tasks are approaching their due date (within 2 days) or overdue. This gives users immediate visual feedback about deadline urgency without opening individual tasks.

Specs

• kanban-board — adds Due Date Status Helper and Due Date Badge on Task Card requirements (2 new requirements, 10 scenarios)

Tasks

Frontend Implementation

• 1. Add dueDateStatus computed helper (src/utils/taskHelpers.js)

  • Takes a task object, returns null | "approaching" | "overdue" based on dueDate vs today
  • Uses date-only comparison (no time component)

• 2. Add due date badge to TaskCard.vue

  • Yellow chip "Due soon" when approaching (within 2 days)
  • Red chip "Overdue" when past due
  • No chip otherwise

• 3. Add CSS styling for badge states

  • Uses Nextcloud theming variables for colors

• 4. Add unit test for dueDateStatus helper

  • No due date → null
  • Future date (>2 days) → null
  • Approaching date (1-2 days) → "approaching"
  • Today → "approaching"
  • Past date → "overdue"
