  Paste Tense — pastetense.app
  One stylesheet for every page. No web fonts, no external resources, no url() to anywhere.
  Colours derive from the brand (paste_tense_documentation/platform_docs/BRAND_README.md):
  dark follows the app's Inkwell theme; light follows the app's light glass — lifted slate, never white.
