Add Jing rear crisis chapter

 - Thirty-ninth battle Fan Castle outer-front route, locking Liu Bei and Guan Yu as required sortie officers while the player chooses five support officers from the twenty-two-officer roster to pressure Pang De, Cao Ren, and Yu Jin
 - Fortieth battle Han River flood route, using Guan Yu's water-control plan across an 80x62 flooded battlefield to break Yu Jin's seven armies and open the Fan Castle siege setup
 - Forty-first battle Fan Castle siege route, using a twenty-two-officer roster across an 82x64 castle battlefield to pressure Cao Ren's gate line, Pang De's desperate cavalry, and Wu's rear-shadow scouts
+- Forty-second battle Jing rear-crisis route, using Ma Liang and Mi Zhu's rear-guard roles across an 84x66 Jiangling ferry battlefield to repel Lu Meng's disguised scouts and expose Mi Fang's wavering rear line
 - Camp progress timeline tab that summarizes Liu Bei's long campaign arc, completed battles, current chapter, latest battle, and next major chapter
 - Tactical sortie preparation panel with battle-specific sortie limits, recommended officers with reasons, class role, named equipment, core stats, bond partner, next-map terrain suitability, deployment preview, formation roles, active bond count, recruited-officer count, reserve roster summary, and readiness advice for each deployable officer
 - Officer collection support in camp, including full roster status, selected/reserve/recommended markers, and post-battle reserve training growth for benched officers
 - Treasure equipment effects wired into battle previews and resolution, including named weapon damage bonuses, defensive treasure mitigation, support recovery bonuses, turn-start charm recovery, and equipment-specific growth bonuses

 ## Next Steps
 
-1. Build the Jing Province rear-crisis follow-up, using Fan Castle's pressure, Wu's river scouts, and the first signs of rear-line collapse as the next campaign tension
+1. Build the Jing Province rear-collapse follow-up, using Lu Meng's infiltration, Mi Fang/Fu Shiren's wavering, and Guan Yu's overextended Fan Castle front as the next campaign tension
-2. Expand Fan Castle aftermath events, including rear guard assignments, river signal choices, siege fatigue, and supply decisions that affect sortie recommendations
+2. Expand Jing rear-crisis aftermath events, including warehouse trust, river rumor choices, officer loyalty checks, and supply decisions that affect sortie recommendations
 3. Expand sortie selection into richer pre-battle officer planning, including explicit reserve drills, class practice, and bond-focused camp assignments
 4. Add a dedicated treasure/equipment management view so players can compare special effects and growth
 5. Keep expanding scenarios through the long campaign instead of treating the current slice as an ending
