# Header / Navigation Redesign

Full header redesign: brand-navy bar, 4px purple accent strip, always-visible logo on mobile, high-contrast nav states, dark-mode as brand constant, and integrated login header. Replaces the current white `bg-surface` header that leaks the semantic surface color into what should be a brand-constant element.

## What changes vs. current implementation

### New / changed

- Header `bg-surface` → fixed `bg-brand-navy` (#012851) — not theme-aware
- 4px accent strip above header: `background: #B4B9FF`
- Nav link colors on navy: inactive 55% white, hover 85% white, active 100% white
- Active indicator: 2px bottom border in brand-mint (#A1DCD8) instead of rgba purple pill
- Mobile: logo always visible left; hamburger icon white (was hidden or missing)
- User avatar: mint background (#A1DCD8) with navy text (#012851)
- Dark mode: `dark:bg-surface` override removed from header — stays navy
- Login page: `isAuthPage` guard changed — shows logo-only header, not `null`
- Language switcher on login: moved into header right slot
- Mobile drawer: opens below navy header, white background, navy text links, mint active indicator

### Kept unchanged

- `AppNav` component structure — only CSS changes
- Sticky header behavior (`sticky top-0 z-50`)
- Max-width container and horizontal padding
- NotificationBell, ThemeToggle, LanguageSwitcher components — only icon color changes
- UserMenu component — only avatar color changes
- Mobile drawer open/close logic
- Admin nav link conditional visibility
- `isAuthPage` derived value — still used, just different output

Issues — desktop

1. ① Background is `bg-surface` (white) — not brand. Every other archival app in this family uses a dark branded header.
2. ② No 4px accent strip at top — missing the canonical brand-purple cap.
3. ③ Active link "Dokumente" uses `rgba(180,185,255,0.15)` on white = contrast ~1.08:1. Completely invisible. WCAG AA minimum is 3:1 for UI components.
4. ④ Logo is navy-on-white — works in light mode but will disappear in dark mode if header ever inherits `#1a1a1a`.
5. ⑤ Dark mode: header flips to near-black (#1a1a1a) — breaks brand consistency. Header should be a brand constant, not a semantic surface.
6. ⑥ User avatar: dark navy circle blends with any dark-mode context and provides no semantic meaning via color.

Mobile issues

- Logo hidden on mobile — brand identity completely lost
- Hamburger icon is dark on white — fine in light mode, breaks in dark
- Header still white — same surface-color problem as desktop

Dark mode rule: The header is a brand element, not a semantic surface. It does NOT respond to the `dark:` variant. Page content behind it switches; the header stays #012851.

- Remove `dark:bg-surface` from header element
- Apply `bg-brand-navy` as a non-dark-variant class

Problem: No logo. The user has zero brand context. On first load, there is no visual cue that this is Familienarchiv. The hamburger icon color (dark navy) will also break in dark mode.

Drawer uses white background with navy text — intentional reversal of the dark header. Active page: mint left border + sand background. Language switcher lives in drawer on mobile (not floating).

Problems: Header is hidden entirely on auth pages. Language switcher floats top-right with no visual anchor — it's a ghost. Users arrive with zero brand context. The page could be any app.

Accent strip + navy header appears on login. No nav links (user is not authenticated). Language switcher lives in header right slot — same position as desktop, consistent muscle memory. The brand is present from the first moment the user sees the app.
Implementation change: In `+layout.svelte`, the `{#if !isAuthPage}` guard currently hides the entire header. Replace with a conditional that renders a login variant of the header (logo + lang switcher, no nav links) when `isAuthPage` is true. Move the `LanguageSwitcher` import into the header for the auth variant. Remove the floating `LanguageSwitcher` from `/login/+page.svelte`.

## Implementation notes

### CSS / Tailwind changes

- Header: replace `bg-surface` with `bg-[#012851]` (or add a `bg-brand-navy` utility to `layout.css`)
- Remove `border-b border-line-2` from header — the accent strip replaces the visual separator
- Add a `<div class="h-1 bg-[#B4B9FF]">` before the nav bar in `+layout.svelte`
- Nav links: replace `text-ink` + `bg-nav-active` with opacity-based white utilities: `text-white/55` inactive, `hover:text-white/85`, `text-white border-b-2 border-[#A1DCD8]` active
- User avatar: swap `bg-brand-navy text-white` → `bg-[#A1DCD8] text-[#012851]`
- Notification badge: add `border-2 border-[#012851]` to badge element
- Dark mode: on the `<header>` element, ensure there is NO `dark:` variant overriding the background

### Component changes

- `+layout.svelte`: split the `{#if !isAuthPage}` guard into two branches — full header (authed) vs. login header (logo + lang only)
- `AppNav.svelte`: ensure logo is always rendered, not hidden on mobile via `hidden sm:flex` or similar
- `AppNav.svelte`: hamburger button — icon color from dark to `text-white/85`
- `AppNav.svelte`: active link class — remove `bg-nav-active`, add bottom border in mint
- `UserMenu.svelte`: avatar background and text color
- `ThemeToggle.svelte`: icon fill/stroke → `text-white/70`
- `NotificationBell.svelte`: icon color → `text-white/75`
- `/login/+page.svelte`: remove standalone `<LanguageSwitcher>` — it moves to the layout header

### CSS variable candidates

- Consider adding to `layout.css`:
  `--header-bg: #012851;`
  `--header-accent: #B4B9FF;`
  `--header-nav-active: #A1DCD8;`
- These are intentionally NOT in the dark-mode `@media (prefers-color-scheme: dark)` block — they are brand constants
- If Tailwind 4 theme is configured, add:
  `brand-navy: #012851`
  `brand-purple: #B4B9FF`
  `brand-mint: #A1DCD8`
  to the `@theme` block in `layout.css`
- No backend changes required
- No i18n key changes required
- No new routes required
