 - For Shardok, start with a single-turn guard status before attempting more complex interception chains

-**Current Follow-Up Priorities:**
- Teach the Shardok AI when to use the Warden evacuation command. The command is valuable when the Warden's side has
-  captured enemy heroes and can secure them by leaving the battle, especially when the battle outcome is uncertain or
-  trending against that side.
- Add the strategic passive custody bonus: each round, prisoners in a province guarded by a ruling-faction Warden should
-  get a small accumulated positive bias toward joining that faction. Prefer storing this as an addition to the existing
-  `factionBiases` entry rather than changing the global `roundsInType` multiplier, so the bonus only reflects rounds
-  actually spent under Warden custody.
- Make tactical AI more protective of heroes at risk of capture when a Warden may be present. Warden evacuation makes
-  captured heroes harder to recover, so the AI should treat exposing high-value heroes to capture as more dangerous than
-  before. This matters even when the AI does not have perfect knowledge that a Warden is in the battle.
