SECONDTHIEF: Every Enemy Carries a Dying Clock

A standalone portrait clock-hunt puzzle in pure JavaScript. Every accepted step spends one second from Vesper Quill and simultaneously burns one second from every living clockbeast. Step onto a beast before zero to transfer only its exact post-burn remainder. Arrive on the final chime and the beast becomes a permanent solid Time Husk before you enter its cell. Claim both Chrono Anchors and escape with time still alive.
