Save / load specification

Game-state persistence and post-load rebuild.

Scope

• Save file enumeration (.sav, .sva, .svb)
• Field-table read/write blocks
• castles.dat tile slice sync (16×0x3200)
• MP save ready-sync and restart-after-load
• Continue-from-lastturn behavior

Evidence

• ../../architecture/save/MODULE.md — core I/O, inf config, UI flow
• ../../architecture/game/MODULE.md — save/load wizard integration

First spec targets

1. Save/load wizard UI flow — screen modes, debounce dispatch, MP wait loop (lotr2_save_wait_mp_ready).
2. On-disk layout — done: see On-disk file format.

Spec pages

• On-disk file format — complete 203-entry field-block map, Region B castle/siege tile slice, read/edit/write algorithm, and file variant table.
