Poem

🐰 I hopped through styles in moonlit cheer,
Turning dusty grays to near-white clear,
Text now shimmers on the darkened theme,
A tiny rabbit's bright CSS dream. 🥕✨

In `@frontend/src/index.css`:
- Around line 24-29: The change overrides shared --color-gray-* tokens, breaking
bg/border gray usages; instead revert the --color-gray-200..700 values back to
the original gray ramp and introduce/override dedicated text variables (e.g.,
--text-gray-200..--text-gray-700) or scope the override to the text utility by
updating the CSS rule that sets text color classes (text-gray-*) to use white in
dark mode; locate the CSS definitions you changed (the
--color-gray-200..--color-gray-700 entries) and replace them with restoring the
gray ramp, then add new --text-gray-* variables or a dark-mode selector that
forces .text-gray-* to rgb(255 255 255 / <alpha>) so bg-gray-* and border-gray-*
usages (referenced by Layout.tsx and NFTContractPage.tsx) remain unaffected.
