v3.0.3: High-Contrast Tooltip Enforcement

Additional Hardening

• Enhanced CSS Specificity: Further enforced tooltip styling with !important declarations
• Bulletproof Styling: Ensured tooltips are 100% visible regardless of theme or CSS cascade
• Production-Ready: Final polish for universal cross-theme compatibility

v3.0.2: Component-Level Tooltip Fix

Critical Fix

• Root Cause: Identified that Radix UI TooltipContent component was using theme-dependent CSS variables (bg-popover/90, text-foreground/80) causing invisible text in light themes.
• Solution: Applied component-level fix with forced dark styling (!bg-[#1e1b4b], !text-white) using !important to override all theme styles.
• Result: Perfect tooltip visibility across ALL 7 themes.
