Method setters, bindings and the nameplate solver now gate their arguments as 1.12.1 does.
- Setters given a non-number raise their own usage line; SetTextHeight, SetFrameLevel, SetMaxLines and SetHistoryLines raise on the values 1.12.1 refuses (`0x87c750`, `0x879628`). XML `historyLines="0"` still loads, through the ring setter (`0x77cd90`).
- Bindings gated by `lua_isnumber` take 1.12.1's miss path: nil, a default, or no values.
- SetLootMethod follows `0x4e92a0`: group and leader gates, threshold argument 2 except for master, 2 on a miss, master names resolved by prefix (`0x493aa0`), errors for an unknown method or looter. SetLootThreshold takes the same gates.
- Quest watches fall back to the last selected quest; MessageFrame times store unclamped and expire to 0 (`0x786323`).
- The placement bound is `0x509dd0`'s 32-bit product, so a zero-width rect no longer panics.
