Improve profile picture and navigation alignment on mobile:
- Position UserHeader fixed 2rem from viewport bottom (avoids browser UI issues)
- Center UserHeader horizontally within hamburger menu
- Add 2rem margin to links wrapper for better spacing
- Align navigation items to flex-start for left alignment
Optimize header link spacing and add visual feedback for active pages:
- Reduce link padding and gap for more compact navigation
- Shorten German labels: "In Saison" to "Saison", "Stichwörter" to "Tags"
- Remove "Tipps" section from navigation menu
Add active page highlighting across all layouts:
- Highlight current page links in red (matching hover color)
- Desktop: animated red underline that smoothly slides between links
- Mobile: static red underline for active links in hamburger menu
- Underline aligns precisely with text width (excludes padding)
Improve transitions:
- Fix color transition to only animate color, not layout properties
- Disable underline transition during window resize to prevent lag
- Underline updates immediately on resize for perfect alignment
Separate the drop shadow from the button wrapper into its own fixed
element with a lower z-index. This prevents the shadow from appearing
over the hamburger menu when it's pulled out on mobile.
- Create separate button_wrapper_shadow element
- Move box-shadow styling to shadow element
- Set shadow z-index to 9 to stay below menu but above page content
- Use fixed positioning with pointer-events: none
Extract language switching functionality from UserHeader into a new
LanguageSelector component. In mobile view, the selector appears in
the top bar next to the hamburger menu. In desktop view, it appears
in the navigation bar to the left of the UserHeader.
- Create LanguageSelector component with local element bindings
- Update Header component with language_selector_mobile and
language_selector_desktop slots
- Remove language selector code from UserHeader
- Update recipe and main layouts to use new component
- Hide desktop language selector inside mobile hamburger menu
