Changelog - v1.5.4 - Shadow Arena

Introducing Shadow Duels — fight real player gladiators deployed to the Public Arena.

A new PvP-lite contract type: fight gladiators owned by other players
Other players can deploy gladiators to the Public Arena from their Ludus
Deployed gladiators appear as Shadow Contracts in your Arena tab, marked with cyan styling and a Globe icon
Shadow opponents are matched within your power range based on your strongest gladiator
A Fog of War mechanic hides the opponent's equipment loadout — you only discover what they carry once combat begins
Scout a Shadow Contract to reveal base stats (costs 1 action + gold), but equipment stays hidden
Shadow Contracts persist in the Arena for 3 days (configurable, previously 1 day)
Rewards are split: attackers earn gold and fame from the fight purse, defenders earn passive gold and fame per win
The opponent's House Crest and Ludus name are displayed on the contract card and in fight history

Shadow Duel fights now appear in the Spectare public feed with dedicated cyan styling
New "Shadow Duels" filter option in the Spectare difficulty filter
Shadow Duel badge with arena icon displayed next to the Victory/Defeat result badge
Opponent's house crest and ludus name shown on shadow fight entries
