- Keep loop counters in FindNextItem/FindPrevItem (prevents infinite recursion)
- Restore FindNextDownItem/FindNextUpItem to original logic:
- Move ONE row, then delegate to FindNextItem if slot empty
- Fix boundary check in FindNextUpItem: use BEQ/BPL for signed comparison
(CMP #$01 : BCS was wrong - unsigned comparison treats $FE as 254 >= 1)
The original design: Up/Down navigate rows, delegate to horizontal scan
if target slot is empty. The loop counters in horizontal navigation
prevent infinite loops when all items are empty.

- Fixed: Journal tilemap not updating by ensuring 5 (Palette/Refresh) flag is set in Menu_Journal and other submenus.
- Fixed: Ocarina menu not clearing main menu selector by realigning Menu_ItemCursorPositions to match Menu_AddressIndex, resolving a data mismatch.
- Fixed: Input entirely breaking in the menu (regression from previous commit) by reverting bash116 update flag from 3 back to 2, which seems to prevent VBlank timing issues.
- Updated Docs/GEMINI.md with recent debugging insights covering processor status mismatch, input polling, VRAM update flags, data table mismatches, and custom NMI handlers.
- Fixed: BG color resetting to untinted value on screen transitions (InitColorLoad2).
- Fixed: Addressing mode error in ColorSubEffect causing incorrect tinting.
- Fixed: Active overlays being cleared when hour advances due to static table lookup and incomplete logic in Overworld_LoadBGColorAndSubscreenOverlay.
- Updated handoff documentation with resolution details.
- Fix IrisSpotlight crash ($00F361): Removed errant $0116/$17 writes
from menu_select_item.asm that corrupted VRAM upload index
- Fix journal stack corruption: Added missing PHB in Journal_CountUnlocked
- Fix P register mismatches: Added SEP #$30 to Menu_RefreshQuestScreen,
Menu_ScrollFrom, Menu_DrawRingPrompt
- Fix MagicBag crashes: Fixed data bank corruption in error path,
fixed uninitialized Y register in cursor movement
- Relocate StoryState from volatile $7C to SRAM $7EF39E
- Add bounds checking to HouseTag_Main jump table
- Use long addressing (.l) for SRAM access in custom_tag.asm
