Slate is the control surface for software that listens to a sleeping satellite and waits. Title-safe frames keep every reading legible; a single magenta pulse marks the instant a link locks — nothing louder, nothing wasted.
Every pass moves through the same calm sequence. Slate draws each state as broadcast evidence — a counter, a waveform, a lock tick — never a dashboard of competing widgets.
The ground station sweeps the band. Carrier appears as a thin trace; the viewport stays dark while the antenna brackets close in.
Signal verified. The one magenta pulse fires — a single tick, an underline on the live caption — and telemetry begins to flow.
As the satellite crosses the horizon, the relay arc carries the link to the next station. The bed records the cue and goes quiet.
Action-safe and title-safe guides are drawn as the interface, not decoration — readings never crowd the edge.
A reserved lower band carries monospaced captions and cue numbers; the current line takes the one magenta underline.
A single thin arc crosses panels and terminates in bracketed antenna marks — the only curve in a hard rectangular field.
Point Slate at a feed, watch it lock, and let the subtitle bed keep the record. No noise, no neon — just the signal you were waiting for.
