S1 MTR Addon 1.2.4 hotfix12
Target: Minecraft 1.21.1 / NeoForge 21.1.x / MTR NEOFORGE-4.1.0-beta.2+1.21.1
MTR dependency: maven.modrinth:XKPAmI6u:9SDO8rYc
Build: Java 21 source and agent bytecode build

Hotfix12 retains MTR's native deviation-based late recovery but restricts it to
the fully-open boarding interval. Opening delay, MTR's 3.2-second opening and
closing animations, and the configured post-close departure delay are fixed.

The core transformer checks the source-level Vehicle operations used by MTR's
automatic-platform logic and refuses to patch an incompatible class.

Hotfix12 corrects the Minecraft 1.21.1 GuiGraphics.drawCenteredString
method descriptor (void return type) used by the advanced settings screen.
