Archive

script

// =====================================================
// Archive Tasks — Heading-Aware + Timestamped
//
// Moves - [x] tasks to ## Archive, grouped under their
// original H2/H3/H4 heading, with creation date (draft)
// and completion datetime (system clock, to the minute).
//
// HOW TO INSTALL:
//   1. In Drafts, create a new Action
//   2. Add a single "Script" step
//   3. Paste this entire file into that step
//   4. Save. Run on any daily draft.
// =====================================================
