feat: let the reader zoom in two steps closer than a week

Events routinely end within a day of each other, and at the old close end of the ladder their bar ends were a few pixels apart — the board being asked the one question it exists to answer and telling the reader to squint. Seventy-two and 108 px/day separate them, and give a one-day event a bar wide enough to read and to tap rather than the 34px every short bar collapses to. The clamp test now reads the ladder's last rung instead of naming 48, so extending it again does not need the test rewritten. Co-Authored-By: Claude Opus 5 (1M context) <[email protected]>
