"""Ask Claude to write the narration and shot list for a product demo video from the product's own web page,
then check every line against that page and against the clock before anyone would record it.

Claude does the work: it reads the page text and returns a few scenes. Each scene has a line of narration,
a shot, a number of seconds, and the sentence on the page that supports the line. Plain code then checks the
work: every quote must be on the page word for word, every name and number in a line must be in its quote,
and every line must be short enough to say in its shot's seconds. The check is ordinary Python, never a
second AI call.

    add --strict to exit 1 when any script is caught (for a scheduled job); add --out <folder> to write elsewhere

Everything the script writes goes to --out (default: the folder this file is in):
  demo_script-answers.json   every request and answer (model id, date, prompt, raw answer, tokens)
  demo_script-results.csv    one row per product: the outcome of the check
  run-view.html              the run, played one product at a time
A --plant-error run writes demo_script-planted-results.csv and run-view-planted.html instead, and never
touches the clean run's files.
