Freight Fate v1.5.0

"On the Clock": hours of service, fatigue, day and night, and overnight
parking. Everything runs on the in-game clock (settings.time_scale
compresses it as usual), never wall time.

Added

• Hours of service. Simplified FMCSA rules per shift: 11 hours of
  driving inside a 14-hour duty window, a 30-minute break required after
  8 hours at the wheel, and a 10-hour sleep to reset. Spoken warnings at
  2 hours, 1 hour, and 30 minutes before each limit (each fires once),
  and at the violation itself. The C key now reports the clock time and
  HOS status alongside the deadline; Tab includes it at normal and chatty
  verbosity. Driving past a limit risks roadside inspections with
  escalating fines (200 to 2,000 dollars) and reputation hits — never a
  game over. A new Settings entry, "Hours of service", picks realistic,
  relaxed (every limit 25 percent longer), or off.
• Rest stop menu. Pressing T at a rest stop now opens a fully spoken
  menu: refuel (as before), take a 30-minute break, or sleep 10 hours.
  Resting advances the in-game clock, so the delivery deadline keeps
  counting — that is the tension.
• Fatigue. Builds with continuous driving (faster at night), eases
  with breaks, and clears with sleep. A drowsy driver yawns, drifts onto
  the rumble strip, hears spoken drowsiness warnings, and reacts late to
  hazards (the reaction window shrinks up to 40 percent). Deterministic
  under the trip seed.
• Day/night cycle. Dawn, day, dusk, and night derived from the career
  clock (new careers still start at 6 AM). Nights bring sparser traffic
  zones, a higher hazard chance, a cricket-and-air night ambience layer,
  and the previously unused "Night Haul" track while driving. V, Tab, and
  C mention the time of day, and arrivals speak the clock ("It is 11 PM").
• Overnight truck parking. Arriving at a rest stop between 8 PM and
  4 AM, the lot may be full — more likely as the evening wears on,
  deterministic per trip seed. A spoken menu offers driving on to the next
  stop or shoulder parking: a full HOS reset but poor rest (fatigue floor
  of 30) and a 15 percent chance of a 150-dollar ticket.
• New manual page "Hours and rest"; F1 help on all new menus.
• New procedural sounds: ambient/night and driver/yawn
  (regenerate with tools/generate_audio.py).

Fixed

• Speech backend selection. Prism's registry ranks NVDA above every
  other backend whether or not NVDA is running, so on machines without it
  the game bound to a dead NVDA connection and stayed silent. The backend
  choice is now validated against actual runtime support and falls down
  the priority list (JAWS, One Core, SAPI, Speech Dispatcher, ...) to the
  best backend that can really speak. A new
  FREIGHT_FATE_SPEECH_BACKEND=<name> environment variable forces a
  specific backend for troubleshooting.

Compatibility

• Save format version is now 3. Old v2 profiles and pre-1.5 mid-trip
  snapshots load cleanly, defaulting to a fresh HOS clock and a rested
  driver.
