Light mode: punchier accent + inverted project logos

- tokens.css: light --text-accent #A52260 -> #C42A6C — a vivid beetroot
  pink (was a livid/dull magenta), still WCAG-AA on white (~5.08:1).
  Applies to the landing wordmark/eyebrows/tags and to docs links in light.
- Landing.vue: project-card logos are now scheme-aware — the inverted
  (dark-ink) -light.svg marks in light mode, cream -dark.svg in dark —
  instead of always using the dark (cream) variant.
