Oikos UX/UI Audit & Implementation Plan

1. Design-System & Styling

Issues Identified

1. Touch Targets Too Small: --target-sm: 32px and .btn--icon-sm (36x36px) violate minimum touch target guidelines (44x44px or 48x48px). This causes usability issues on mobile devices (fat-finger syndrome).
2. Duplicated Dark Mode Tokens: Dark mode CSS variables in tokens.css are duplicated across @media (prefers-color-scheme: dark) and [data-theme="dark"], creating a maintenance nightmare.

Implementation Steps

• Fix Touch Targets: --target-base: 44px Token ergänzt; .btn--icon-sm auf min-height/min-width: var(--target-base) korrigiert; --target-sm bleibt 32px als visuelle Größe (kein Touch-Target).
• Refactor Theme Tokens: Bewusst übersprungen — der CSS-native @media (prefers-color-scheme: dark)-Block ist eine Stärke (Dark Mode ohne JS). Entfernen würde Nutzer ohne JS ohne Dark Mode lassen.

2. Components & Interaction

Issues Identified

1. Mobile Modal Swipe-to-Close Bug: If a user drags the modal down (dy > 0) and then back up (dy < 0) without lifting their finger, dragging is set to false. The touchend event is then ignored, leaving the modal stuck out of position.
2. Accessibility (A11y) Violation: The .modal-overlay element uses role="presentation" alongside an aria-label. role="presentation" hides the element from screen readers, conflicting with the label and its function as a clickable close area.
3. Misplaced Utility Functions: Generic UI helpers (wireBlurValidation, validateAll, btnSuccess, btnLoading, btnError) are hardcoded in pages/dashboard.js instead of a shared utility file.

Implementation Steps

• Fix Swipe Bug (modal.js): touchmove-Handler korrigiert — bei dy < 0 wird Panel auf translateY(0) zurückgesetzt, dragging bleibt true.
• Fix Modal A11y (modal.js): role="presentation" aus .modal-overlay entfernt.
• Relocate Utilities: Bereits erledigt — wireBlurValidation, validateAll, btnSuccess, btnLoading, btnError sind in utils/ux.js (Zeilen 538–620).

3. Layout, Navigation & Routing

Issues Identified

1. FOUC (Flash of Unstyled Content) on Navigation: In router.js, loadPageStyle removes the old stylesheet before the new page transition animation (page-transition--in-right) completes, causing layout jumps.
2. Missing Focus Trap in Global Search: The #search-overlay does not use the focus trap logic from modal.js. Users can tab out of the search overlay into the hidden page below.
3. SVG ID Collision Risk: The logo generated in router.js uses a hardcoded ID (id="oikos-logo-bg") for its gradient. If reused, this will break rendering.

Implementation Steps

• Fix Routing FOUC (router.js): Kein echter Bug — style.cleanup() wird vor module.render() aufgerufen, aber die neue Seite startet opacity: 0. Kein sichtbares FOUC in der aktuellen Implementierung.
• Add Search Focus Trap (router.js): Eigenständiger Focus Trap in openSearch/closeSearch implementiert (ohne modal.js-Kopplung).
• Fix SVG IDs (router.js): Gradient-ID wird nun mit Math.random().toString(36)-Suffix generiert.

4. Dashboard

Issues Identified

1. Wasted Space from Large Empty States: Empty widgets (e.g., no tasks) render a large "Empty State" UI. On mobile, this pushes populated widgets below the fold.
2. Lack of Visual Feedback in Customization: Reordering widgets in the customize modal (rebuildList()) happens instantly without transition, feeling jarring.

Implementation Steps

• Compact Empty States (dashboard.js): Offen — .widget__empty hat bereits reduziertes Padding (space-5), aber kein echtes Row-Layout. Niedrige Priorität.
• Animate Widget Reordering (dashboard.js): Offen — View Transition API wäre sinnvoll, aber kein Bug. Niedrige Priorität.
