IntelHUD no longer builds #intel-hud with innerHTML or writes its readouts by id: it publishes its readouts, typing summary, REC blink, visibility, layout variant and style colors through its publish option to the gev-hud store, and the intel-hud application view renders them. The corners render from mount so the panel layout controllers register them as obstacles. The vessel layer presents the selected vessel's readout through src/hudReadouts.js, which IntelHUD follows, instead of writing into the HUD. The Cyber sonar state answers a HUD toggle from IntelHUD's visibility rather than the class the view renders on its next update.

// The HUD's LAT/LON readout in degrees-minutes-seconds. Seconds are printed to

// two decimals, so a value within 0.005" of the next whole minute rounds up.

// That carry must reach the minutes (and degrees): `122°20'60.00"W` is not a

// coordinate. Ordinary decimal inputs land there through binary floating
