Decision 1 keeps the unmodified single-key bindings, and Settings was the only place they were written down — three of the four categories of them, because config-page listed the categories by hand, so the autotag keys were written down nowhere at all. `?` now opens an overlay from anywhere the app owns the keyboard, and both surfaces read one table (services/shortcut-meta.ts, moved out of config-page's private static). The other half is the same explanation from the other side. Phase 1 gave the arrow keys to the grid, correctly — but all six of them, and no list in this app moves horizontally: track-list's own handler and utils/roving-rows both take Up/Down/Home/End and ignore Left/Right. So seeking stopped working from a focused row and nothing gained the keys. Reproduced in the running app: two ArrowRights on a focused track row, zero Player.Seek calls, against one per press from the body. A shifted character no longer reports Shift, so the binding is `?` and not `Shift+?` — the character already carries the shift, and a layout where it does not is a layout where "Shift+?" is wrong anyway.
