A brush across the grid opened whichever photograph was under it. Travel
was already answered — the Flickable claims the pointer and the press is
cancelled — but a contact that neither travels nor lasts reaches a
TouchArea as an ordinary press and release, and it was landing the user
in develop.
So a finger now has to stay down for `TAP_MIN_MS` before letting go
counts as opening anything. That is the floor under a tap where the 450 ms
`HOLD_DELAY_MS` is the ceiling: below is a graze, between is a tap, above
is a hold that starts a selection. One scale, three gestures.
Only a finger is held to it. A mouse click is a discrete decision made by
a button and is routinely over in thirty milliseconds, so `cell-pressed`
now reports whether a finger did it — the same finger-id convention the
pinch arbitration beside it already uses — and the dwell applies to touch
alone.
A graze still *selects* the cell it landed on, because the press already
did that. That is the right failure mode: something visible and
reversible rather than a silent nothing, and rather than develop.
