/* Appendix 03.1, Local Historian. Scoped to main.ch31 so it can join the index's document on a
   page turn. Two kinds of type live here: D's (the frame, its captions, the cover) and Local
   Historian's own (inside .lh-copy: IBM Plex Mono headings, Inter body, slate and amber), so
   the screen reads as the other site, shown inside this one.
   Without motion (no .live) the film section is a list: each poster, its copy beside it.
   With motion (.live, added by appendix-lh.js) it is a pinned stage with the film on a canvas. */
