Fix
GitHub and Anthropic icons fixed in dark mode
Both brand icons used near-black hex values that disappeared on dark backgrounds. Fixed to use currentColor.
The GitHub and Anthropic icons were effectively invisible in dark mode. Both SVGs were hardcoded with near-black fill values (#1a1a1a and similar) that rendered fine on white but disappeared entirely on a dark background.
Fixed both icons to use currentColor instead. They now inherit the text color of their parent element, so they render correctly in both light and dark mode without any additional overrides.
No design changes — they look identical in light mode.
