3. Confirmed Visual Differences (3)
Missing Glassmorphism Blur on Header
SafariHigh
The sticky header has `backdrop-filter: blur(12px)` which fails in WebKit because `-webkit-backdrop-filter` prefix is missing.
Chromium
Safari
Firefox
Suggested Fix: Add `-webkit-backdrop-filter: blur(12px);` to `.sticky-nav`.
Button Background Gradient Clipping
SafariMedium
Rounded border corners fail to clip linear background fill when combined with nested transforms.
Suggested Fix: Apply `overflow: hidden` and `-webkit-mask-image: -webkit-radial-gradient(white, black)` to CTA button container.
SVG Stroke Clipping at Border Boundary
FirefoxMedium
SVG icon strokes on the top right navigation toggle clip along the viewBox boundary due to missing overflow styling.
Suggested Fix: Set `overflow: visible` on the SVG root node.
4. Visual Fix Recommendations
| Element / Property | Browser Difference | Practical Correction | Expected Result |
|---|---|---|---|
| .sticky-nav / backdrop-filter | Transparent surface without blur in WebKit | Add -webkit-backdrop-filter: blur(12px); alongside standard declaration. | Frosted glass appearance consistent across all three browsers. |
| .btn-primary / border-radius | Corners unclipped on Safari during active state | Add overflow: hidden; transform: translateZ(0); to .btn-primary. | Clean rounded pills with no sharp corner artifacts. |
| .nav-icon-svg / overflow | Right stroke edges clipped in Firefox | Set overflow: visible; stroke-linecap: round; on SVG icon. | Unclipped crisp iconography across all viewports. |
5. AI Visual Fix Prompt
Fix visual discrepancies between Chromium, Safari, and Firefox:
1. In .sticky-nav: add `-webkit-backdrop-filter: blur(12px);` to support Safari WebKit.
2. In .btn-primary: add `overflow: hidden; transform: translateZ(0);` to eliminate corner bleeding in Safari.
3. In .nav-icon-svg: add `overflow: visible;` so Firefox does not clip stroked SVG edges.
Ensure no layout regressions in Chromium or Firefox.
