Replace the single-spout bounce animation with two independent `╭───╮`
arcs sweeping at different speeds across a calm `─` water surface. Add
`footer_working_label` to pulse `working` → `working...` at 400 ms
cadence while a turn is live. The dot-pulse fires even in low-motion
mode; the arc strip is gated behind `!app.low_motion`. Frame math is
purely deterministic so the test suite can pin specific frames.
