feat(tour): everyone takes the tour once, and tries the layouts in it

The tour now floats over the page it describes and must be finished
before the app can be used: new readers straight after setup, returning
readers on their next visit, and anyone who saw the earlier tour. The
page behind stays visible and scrollable but inert.

"Pick a layout" (on the Checklist) and the Timeline step switch Relaxed /
Structured and New / Classic in place; the selected look is kept.
Returning readers start on Relaxed. A replay from Settings stays
optional and closable.

redesignTourSeen now records new / returning / replay / 2026-10-tour-2;
any other value means not yet taken.

+## Round: the forced tour and trying the looks (2026-10-18)
+
+The owner asked for every reader, new and returning, to be put through the tour before they can use
+the app, and for returning readers to start on Relaxed. "Pick a layout" (Checklist) and the Timeline
+step switch the page behind in place, and the selected look is kept. See `docs/DESIGN.md` → "The tour"
+and `docs/DATA-MODEL.md` for the `redesignTourSeen` values.
+
+Schema review: no data-loss or stuck-state path. Accepted, by the owner's rule: a returning reader who
+had picked Structured on purpose is moved to Relaxed once, and the previous value isn't kept. The tour's
+layout step puts it back in one click. Left as is (low): a stale second tab can re-force the tour
+once, and a save-error banner shown during a forced tour can be read but not clicked.
