Enhance eyedropper with live Pantone matching tooltip
pick_color.js: on hover shows a floating tooltip with: - 40px color swatch of the sampled pixel - Hex (#RRGGBB), RGB, and HSL values - Nearest Pantone name and swatch from the database - ΔE value (CIE76 color distance in LAB space) - Quality badge: Excellent (<2) / Good (2-5) / Fair (5-10) / Poor (>10) - Warning note when ΔE > 10 (color cannot be faithfully printed as Pantone) Click copies hex to clipboard and sets as active color (existing behavior). color_utils.js: hexToRgb, rgbToHsl, sRGB→XYZ→CIE LAB conversion (D65), CIE76 deltaE, nearestPantone() (scans all ~350 entries, returns best match). Pantone database is pre-converted to LAB at module load for fast scanning. pantone_colors.js: ~350 representative PMS colors across reds, oranges, yellows, greens, teals, blues, purples, magentas, browns, grays, black/white. Hex approximations from open-source Pantone datasets (not official Pantone data). https://claude.ai/code/session_01B58MaJCU1R6KwBDJCp8AfN
