UI Improvement Pass — Design Spec

Date: 2026-03-19 Scope: All 6 pages — visual polish + UX usability, equal weight Direction: Darker, cooler blue-grey tone ("monitoring dashboard" feel), lifted nav branding

---

Goals

1. Replace the generic default-Vuetify color palette with a distinctive monitoring-dashboard identity
2. Give the nav drawer meaningful visual structure and branding
3. Add a WebSocket connection indicator in the app bar
4. Improve Dashboard information hierarchy and action bar layout
5. Fix dark-mode-breaking hardcoded colour classes across all pages
6. Consistent empty states and loading treatment throughout
7. Per-page UX improvements (Downloads filter, Credentials visual state, Subscriptions dark mode)

Section 1: Color System (frontend/src/plugins/vuetify.js)

Replace both theme palettes entirely.

Dark theme (primary use case)

dark: {
  dark: true,
  colors: {
    background: '#0F172A',   // slate-900 — deep navy
    surface:    '#1E293B',   // slate-800 — card surfaces
    primary:    '#60A5FA',   // blue-400  — cooler accent
    secondary:  '#94A3B8',   // slate-400
    error:      '#F87171',   // red-400
    warning:    '#FBBF24',   // amber-400
    success:    '#34D399',   // emerald-400
    info:       '#38BDF8',   // sky-400
  },
}

Light theme

light: {
  dark: false,
  colors: {
    background: '#F1F5F9',   // slate-100 — cool grey workspace
    surface:    '#FFFFFF',
    primary:    '#2563EB',   // blue-600 — deeper, more serious
    secondary:  '#475569',   // slate-600
    error:      '#EF4444',
    warning:    '#F59E0B',
    success:    '#10B981',
    info:       '#0EA5E9',
  },
}

Global component defaults (add to existing defaults)

VCard:  { elevation: 0, border: true },
VBtn:   { variant: 'flat' },
VChip:  { rounded: 'md' },

Removing shadow elevation in favour of a subtle border gives cards a cleaner, more modern feel at both themes. The border adapts to theme colours automatically.

---

Section 2: Nav Drawer & App Bar (frontend/src/App.vue)

Nav drawer brand header

Replace the plain v-list-item brand block with a styled header:

• Container: pa-4 padding, bg-surface background to visually separate from nav list
• Icon: mdi-download-network at size 32, color="primary"
• Title: "GallerySubscriber" in font-weight-bold text-subtitle-1
• Subtitle: "Download Manager" in text-caption text-medium-emphasis
• Followed by a v-divider

Nav list items

Change from density="compact" to density="comfortable". Add rounded="lg" and active-color="primary" to each v-list-item. The built-in Vuetify active state renders a tinted pill highlight on the current route.

App bar

• Change elevation="1" to elevation="0" with border="b" — flat bar with bottom border
• Add a WebSocket status indicator to the right of the title, before the theme toggle:
  • A v-chip or icon+dot combination showing three states:
    • Connected: small green dot (color="success") + tooltip "Connected"
    • Connecting: amber dot with CSS pulse animation + tooltip "Connecting…"
    • Disconnected: red dot + tooltip "Disconnected — real-time updates paused"
  • Reads from useWebSocketStore().status (the store already tracks connection state)
  • variant="text" so it's unobtrusive

---

Section 3: Dashboard (frontend/src/views/Dashboard.vue)

Stat cards (number-forward layout)

Replace the v-avatar + side-by-side number layout with a vertical number-forward design:

• Large text-h3 font-weight-bold number at top
• text-caption text-medium-emphasis label below
• A 4px left border accent stripe using inline style border-left: 4px solid <colour> matching the card's semantic colour (primary, success, error, warning)
• Remove the v-avatar entirely — the border provides the colour signal

Action bar (split into two rows)

Row 1 (actions): The three action buttons unchanged — Check All Sources, Retry All Failed, Reset Stuck.

Row 2 (status): Two groups separated by a v-divider vertical:

• Left: credential status chips (the existing platform chips, unchanged)
• Right: storage stats (existing display, unchanged)

Each row is its own v-card-text. This removes the single-line cramming.

Active downloads list

Running items get a subtle animated left border:

.download-running {
  border-left: 3px solid rgb(var(--v-theme-primary));
  animation: pulse-border 2s ease-in-out infinite;
}
@keyframes pulse-border {
  0%, 100% { opacity: 1; }
  50%       { opacity: 0.4; }
}

Consistent empty states

All three empty panels (active downloads, recent activity, sources needing attention) use the same pattern:

<div class="text-center py-8">
  <v-icon size="48" color="medium-emphasis">mdi-[relevant-icon]</v-icon>
  <div class="text-body-1 mt-2">[Primary message]</div>
  <div class="text-caption text-medium-emphasis mt-1">[Helper text]</div>
</div>

• Active downloads empty: icon mdi-check-circle-outline, "No active downloads", "All sources are idle"
• Recent activity empty: icon mdi-history, "No recent activity", "Failures and new downloads appear here"
• Sources needing attention empty: icon mdi-check-all, "All sources healthy", "No failures in the last 7 days"

---

Section 4: Per-Page Fixes

Subscriptions (frontend/src/views/Subscriptions.vue)

• Replace class="bg-grey-lighten-4" on the expanded inner table with class="bg-surface". This is the only dark-mode-breaking class in the file.
• Add class="border-t" to the inner table container for visual separation.

Downloads (frontend/src/views/Downloads.vue)

• Add an exclude_superseded toggle to the filters row: a v-switch or v-chip labelled "Hide superseded failures" that adds exclude_superseded: true to the fetch params when active. Defaults to true (consistent with the dashboard behaviour).
• No table layout changes.

Credentials (frontend/src/views/Credentials.vue)

Two visual states for platform cards:

Configured: Card gets border-color set to the success colour via inline style or a CSS class. Existing content unchanged.

Not configured: Card gets a dashed border (border: 2px dashed), the v-alert info block is replaced with a concise empty-state message, and the "Add Credentials" button is promoted to color="primary" variant="flat" (currently variant="text"), making the call to action visually prominent.

Settings & Logs

No structural changes — both pages inherit the new palette and card border style from the vuetify.js update automatically.

---

Files Changed

File	Change
frontend/src/plugins/vuetify.js	Full palette replacement, component defaults update
frontend/src/App.vue	Nav branding, nav item density/rounding, app bar border+ws indicator
frontend/src/views/Dashboard.vue	Stat card layout, action bar split, running item pulse, empty states
frontend/src/views/Subscriptions.vue	Replace bg-grey-lighten-4 with bg-surface
frontend/src/views/Downloads.vue	Add exclude_superseded filter toggle
frontend/src/views/Credentials.vue	Configured/unconfigured card visual states

Settings.vue and Logs.vue are not modified — they benefit from the theme update without code changes.

---

Non-Goals

• No new pages or routes
• No layout restructuring (grid columns, page structure unchanged)
• No new API endpoints
• No component extraction / shared component library
• Settings.vue and Logs.vue: no structural changes
