In T421131 we implemented an average color & contrasting color generation for the background and foreground text, but left tinting of the wordmark and license icon SVGs to be finalized in a follow-up task. This is that follow-up task. :)

wordmark is accent colour at 50% opacity
CC icons and attribution text are accent colour at 25% opacity

Acceptance criteria:

• Average-color mode should use the contrasting color to tint pixels in the wordmark and icon SVGs.
  • This can be achieved using CSS/SVG filters.
• Light mode should tint the wordmark and license icons to black/gray.
• Dark mode should tint the wordmark and license icons to black/gray and then invert it to produce white/gray.
• Transparent mode should follow Light mode (todo: double-check with design)
• All four style variants must work according to spec on both "light mode" and "dark mode" Minerva themes. See also T421131#11830668
• All four style variants must appear correctly in the generated image as well as in the preview.
