Ryan Malloy b57b8beb50 Fix dark theme contrast — correct Starlight gray ramp direction
Starlight uses gray-1=lightest, gray-6=darkest in BOTH modes.
The initial theme had the dark mode grays inverted, causing body
text (gray-2) to resolve to near-black on a dark background.
Also adds proper light mode overrides with inverted semantics.
