   film.css — the hero film: one PlansFlow project, live (v1, 2026-09-24)
   --------------------------------------------------------------------------
   The hero figure is not a video. It is a working replica of the PlansFlow
   workspace in plain HTML and CSS, driven by film.js on a 20.6 s loop: the
   canvas, the console band, the prompt panel and its thread, blocks,
   selection and connections. A "camera" moves over the replica the way a
   screen recording zooms, so the chat reads in close-up and the board reads
   in the wide shot.

   Source of truth for every value below (nothing is invented):
     prompt panel   app  src/styles/prompt-panel-v2.css  (.pb-*, ported
                    verbatim where the film uses it, scoped to .pff-app)
     blocks         app  src/styles/canvas.css (.pf-img-rail, selection,
                    image frame), text-block.css (.pf-text),
                    note-block.css (.pf-note), YouTubeBlock.tsx,
                    LinkCardBlock.tsx, ConnectionLine.tsx
     band           Desktop/PlansFlow Canvas Console Mockup/console.css,
                    as the live app renders it (flanks 132 px, 16 px gaps,
                    measured on the owner's 2026-09-23 screenshots)
     header         app  src/components/Layout/Header.tsx
     tokens         app  src/styles/base.css (.dark)
   App fonts are used inside the replica on purpose (Inter, Roboto Mono,
   the system sans of text blocks, Clepto for the wordmark); the page loads
   them already. The film is dark in both site themes, like the canvas demo
   in section 01: it is the product, in its own colours.
