SYSTEM REQUIREMENTS
  - Computer: A Windows 10 or 11 PC, or a Mac with a current macOS.
  - Browser: A current version of Chrome, Edge, Safari or Firefox.
  - Folder: The ZIP extracted to a folder on the computer, such as Documents.
  Not opened from inside the ZIP, an email or a synced folder.
  - Size: A kit ZIP is about 1 to 5 MB; bundles and the Practitioner master
  are larger. Allow 40 MB once extracted.
  - Screen: A desktop browser window on a laptop or desktop screen.
  - Not supported: phones, tablets (iPads included) and Chromebooks. Virtual
  desktops (Citrix and similar) work only if the browser keeps its saved data
  between sessions, so save a work file before you sign out.

PLEASE ALLOW, FOR THE USER'S ACCOUNT
   1. Opening local .html files (file://) and running their scripts.
   2. Browser storage (site data) for those local files, kept between
   sessions.
   3. Downloads to a folder the user can reach, for work files and exports.
   4. The file picker, to open a saved work file or a spreadsheet to import.
   5. In-page pop-up windows (the browser’s dialog element).
   6. Printing, including Save as PDF.

DOWNLOADED FILES
Downloaded on Windows? Before you extract it, right-click the ZIP, choose
Properties, tick Unblock and press OK, so Windows stops treating the files
inside as blocked internet downloads. On a Mac, double-click the ZIP to
extract it; if macOS warns that a file came from the internet, choose Open, or
ask IT to clear the quarantine flag on the kit folder.
