- Add a persistent toggle in the header (saved to localStorage) - Swap green/yellow tile colors for a blue/orange colorblind-safe palette (the combination hardest to distinguish for the most common types of color vision deficiency) - Add shape cues (filled circle for correct, diamond for misplaced) on tiles in colorblind mode so state doesn't rely on color alone - Add aria-label status text to guess cells for screen readers Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Summary
This repo had no colorblind mode at all — just a fixed green/yellow/gray tile scheme, which is one of the hardest color combinations for deuteranopia/protanopia (the most common forms of color vision deficiency).
