 - [x] Add server-authoritative fire spread rules for grass, brush, trees, shelters, and other burnable actors, including fuel, distance, wind, weather, and suppression hooks. Added replicated grass, forest, and structure fire intensities plus active spread radius that grow only on the server from nearby fuel, ignition distance, wind/weather, and a suppression-pressure hook for later rain, carried water, dirt/sand, firebreaks, and tools.
 - [x] Add fire maintenance gameplay so watched, cleared, contained, or extinguished fires are safe, while neglected fires can become dangerous. Updated lit campfire interaction to maintain the fire, added watch, clear-area, and contain-fire hooks, and made maintenance reduce campfire, vegetation, forest, and structure ignition risks while extinguishing resets active risk state.
 - [x] Add fire suppression hooks for rain, water carrying, dirt/sand, cleared firebreaks, and future firefighting tools. Added shared server-side suppression hooks plus water, dirt/sand, firebreak, and tool wrappers that raise suppression pressure, reduce ignition risks, reduce active fire intensity, shrink spread radius, and let rain/water drain fuel.
-- [ ] Persist active grass, forest, and structure fires across save/load without corrupting world state.
+- [x] Persist active grass, forest, and structure fires across save/load without corrupting world state. Extended campfire persistence coverage for ignition flags, ignition risk scores, active grass/forest/structure fire intensities, spread radius, and suppression pressure so save/load recovery preserves active and partially suppressed fire state.
 - [ ] Add QA coverage for safe campfires, unsafe campfires, vegetation spread, shelter ignition, suppression, and save/load recovery.
 - [ ] Add weather sounds.
 - [ ] Add wildlife sounds.
