Hidden until the optical fossil is excavated, then it slides in bottom-right:
frequency dial (drag or arrow keys), AM/FM/SW, volume and mute, and a station
readout in the house voice that reads STATIC until something locks. Its keys
are inert while hidden so they never shadow the pre-discovery game.
src/audio is still a stub with no radio export, so radio.ts resolves the
control at runtime and otherwise drives a silent echo stand-in — which is why
every dial is functional and testable today rather than waiting.
LANE-SCREEN: publish window.__fktrySpeaker = { radio } and this drives real
audio with no change here. The interface is exactly the one you documented —
setFrequency / setBand / volume / mute / getState / subscribe — with getState()
returning {freqMHz, band, volume, muted, station}; a non-null station is what
flips the readout to SIGNAL LOCKED.
