// Every recorded radio clip: who says it, what they say (as spoken), and the subtitle.
// tools/voices/build.ts renders these with Piper into src/assets/radio-voices.bin; edit this
// file and re-run `bun tools/voices/build.ts` to change what the radio says.
//
// Written the way people actually talk on the radio: short phrases with commas for the
// breaks, the odd "uh", contractions. Numbers always sit inside a whole sentence (never
// stitched in as separate words), so the intonation carries through them.
// `urgent` lines are rendered faster and higher, like someone who's excited.
