CHANGELOG
=============================================================
TAK versioning mirrors AR versioning from v2.20 onward.

=============================================================

TAK-2.25 / AR-2.25 (2026-05-04)
- Fixed plan start date and available week count being wrong for
  non-Sunday races. planStartDate() was subtracting weeks×7 from
  the raw race date, assuming races always fall on Sunday.
  For a Friday race (Jul 24), week 11 landed Jul 13–19 instead of
  Jul 20–24, printing Jul 17 as the race date.
  Fix: new raceMondayDate() finds the Monday of the race week.
  All calculations now anchor on this:
    planStartDate = raceMonday - (weeks-1)×7
    weeksAvailable = floor((raceMonday - nextMonday) / 7) + 1
  For May 4 start + Jul 24 Friday race:
    - 12-week plan starts May 4, race correctly on Fri Jul 24 ✓
    - 11-week plan starts May 11, race correctly on Fri Jul 24 ✓
  Calendar earliest date also corrected to (min-1)×7.

TAK-2.24 / AR-2.24 (2026-05-04)
- Fixed nextMonday() skipping a week when today IS Monday.
- Print table cells show calendar date top-right ("May 4th" format).

TAK-2.23 / AR-2.23 (2026-04-23)
- Session distances snapped to nearest 0.5 km/mi.
- Print descriptions rebalanced.
- 30K label threshold fixed (≤21.0mi).
- Stat card contrast and spacing improved throughout.

TAK-2.22 / AR-2.22 (2026-04-23)
- Race Name field added.

TAK-2.21 / AR-2.21 (2026-04-23)
- Race week built around actual race day of week.

TAK-2.20 / AR-2.20 (2026-04-23)
- Gradient caps per session type for trail plans.

TAK-2.19 / AR-2.19 (2026-04-23)
- Race week elevation fixed; syncF() fixes.

TAK-2.18 / AR-2.18 (2026-04-23)
- Trail LR elevation 45%; nearest 100m rounding.

TAK-2.17 / AR-2.17 (2026-04-23)
- Fixed elevation formula ignoring race elevation.
