Frame posture public door๏ƒ

๐ŸŸ  Advanced ยท Lesson 03

Frame POSTURE through the public door. configure_aether_frame() is the manual fluent path: set the world's system_state BEFORE anyone conjures, and every conjure then INHERITS it - no dynamic=True flag needed anywhere (the settle-then-inherit law from intermediate 21, driven from the configuration side this time). The posture FREEZES at the first conjure: configuring after that refuses - a world's mode is decided once.
