/* ============================================================
   PRIMENESS: Field Survey page, "living sheet" (#sample, T-204)
   Each stop of the featured sheet plays its own scene on the drawing
   (assets/js/fs-live.js). Two layers:
     .fs-lv      SVG inside the camera, in sheet units (1632 x 1056),
                 so it zooms with the drawing
     .fs-lv-pop  HTML over the stage (above the dim), for the pieces
                 that lift off the paper: flip card, spreadsheet, fan,
                 gauge, floor plan
   Colors (DARK PAPER, 10/7): the sheet is the dark render (make_dark.py): paper #0F1013, ink #E8E8EC,
   lime stays lime. Highlights use 'screen' so the light text stays readable.
