v2.32.0: Readable severity, a designed report on every install, and report styling that can't hide what a report says

• Severity is easier to read in reports. High, medium and low severity words and graph markers
  are darker, so each meets the standard contrast for small text. High and medium used to fall
  below even the large-text minimum.
• Every install gets a designed report. Unbranded reports used to be near-unstyled text. They
  now use the full layout in a neutral theme, and each file is about 96% smaller. Branded reports
  are unchanged.
• A report's styling can't hide what it says. It now comes from a theme the skill checks first,
  so all text stays readable, including how current the data is. A theme that fails is set aside,
  and the report says why.
