Unify TOC ownership, real video episode list, slider overlay, single-query related list, Zibll user-card after-box, and new-route subtitle/meta contracts.
Restore Zibll float dual-column shell, fix single settings DTO key mapping,
reorder article footer/actions, and match author bar, prev/next, title/body
typography, and limit-height expand UX.
Wire pay_box_position to box_top/top/bottom/box_bottom, render download or
paywall modules at those slots, and resolve featured_slide/attachment IDs
plus video episode chrome for single covers.
Honor prevnext/authordesc/yiyan settings, multi-tax related queries with
orderby (incl. views), per-post maxheight override, and only expand content
when maxheight is enabled.
