From a person photo, a background and a topic, produces one cover per aspect ratio each target platform needs (3:4 / 4:3 / 16:9 / 9:16, optionally in two languages), re-laid-out per ratio rather than stretched, each file's real pixels checked, filed by date. Cover text is defined by /aikey-title and passes the red lines. Makes images only, never publishes. Not for: deciding the cover text (aikey-title), editing the video (aikey-cut). Trigger: /aikey-cover, "make video covers", "covers in every size", "bilingual covers" —— AI KEY · 不给公式，给判据。每条规则都标了实测代价。" Observed in sandbox: no network, touches nothing outside the project, writes no memory.
