Study Start Date
By default, deadlines and planner.html's calendar are projected forward from today, recomputed fresh every time the page loads — see help.html. Setting a start date here fixes that anchor instead: the schedule projects forward from this date rather than always sliding to today, so falling behind pace shows up as overdue rather than quietly re-basing.
Study Pace
By default, deadlines on index.html/plan.html
and item placement on planner.html are auto-calculated from a fixed
formula — see help.html for the details. Use this page to
override the two numbers that formula runs on, without hand-editing any file. The override is
stored in this browser's localStorage only (same scope as checklist progress) — a
different browser or machine keeps using the defaults from assets/plan-data.js until
set here too.
