Wire Zibll-style board sort tabs, shared topic rows, page-template
URLs, forum asset enqueue on home/plate, home synthesis load-more,
and topic last_reply meta for last-reply ordering. No dual-read.
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.
Apply comments_template_query_args for newest/hottest/author-only,
keep filter bar visible under empty author filters, and restyle order
tabs/buttons with Zibll-compatible classes.
Render full search overlay with types/history/suggestions for tabbar
and desktop header toggle. Open panel on all viewports (not mobile-only)
and wire data-toggle-class/.navbar-search compatibility hooks.
