Live-measured on docker-dev: the backdrop was viewport-wide (1911px) but started at the panel's left edge (241px) because the theme's .rise animation (fill-mode both) leaves an identity transform on section.panel, re-basing position:fixed descendants. Override the fill mode to backwards; drops the speculative backdrop/dialog sizing overrides. Claude-Session: https://claude.ai/code/session_01Ef2ozxS7QPanGT8uoATbTe
