gh-142927: Tachyon: Fix contrast ratio in top panel by hugovk · Pull Request #142936 · python/cpython

Ah right, thanks. Let's update those too.

They should be at least 4.5 to meet WCAG AA guidelines.

Actually, that's for normal size text. The heatmap panel is large, so the original colours are at least 3.

We need 4.5 for the flamegraph, and it's hard to find colours that work for both dark and light themes. So this is now updated to different colour for dark/light and re-use via variables.

Also we don't need stat-card for 5th and 6th children, rate-card is used instead. So delete that dead code.
