fix: Differentiate zoom and info button colors, fix button visibility in responsive mode
Issues fixed: 1. Zoom button now uses purple color (rgba(155, 89, 182, 0.7)) instead of blue 2. Info button keeps blue color (rgba(52, 152, 219, 0.7)) 3. Both buttons now show distinct colors in default state, not just on hover 4. Device detection now considers viewport width, not just user agent 5. Buttons no longer hide in responsive mode at desktop viewport sizes Changes: - Updated zoom-toggle-btn to use purple background color - Updated info-button to use blue background color (explicit, not var) - Modified device-detection.js to check viewport width (≤900px) in addition to UA - Added resize listener to update device class dynamically - Created test (67-button-colors-and-visibility-test.mjs) to verify fixes Testing: - Desktop (1278px): All buttons visible with distinct colors - Mobile (375px): Zoom/shortcuts hidden, core buttons visible - Device detection now viewport-aware (prevents hiding at desktop sizes)
