# ArchNest — Design Decisions & Lessons Learned

> This file captures all visual/UX decisions made during Glance page development.
> Apply these consistently to ALL future pages to avoid repeated iteration.

## Global Rules (Apply to Every Page)

### Sidebar
- **Expanded width**: 200px (matches mockup proportions — needs room for labels)
- **Collapsed width**: 64px (icon only)
- **User can manually collapse/expand** via toggle button (not just responsive)
- **Main content margin-left** must match sidebar width exactly

### Page Title (Top Bar)
- **Color**: Gold (#C8A434) — NOT white. Use inline `style={{ color: '#C8A434' }}` if Tailwind class doesn't apply
- **Font**: 18px, bold, uppercase, tracking-wide
- **No border on top bar** — blends into the page background

### Colors — Use Inline Styles When Tailwind Fails
- Tailwind v4 `@theme` custom colors (text-gold, bg-card, etc.) may not always apply
- If a color isn't rendering correctly, fall back to inline `style={{ color: '#C8A434' }}`
- Always verify visually after changes

### Content Alignment
- **All rows must share the same horizontal padding** (`px-6` applied once at the parent container level)
- **Do NOT** use different padding for different rows — this causes misalignment
- The hero banner, status cards, middle row, and bottom row must all line up left and right edges

### Hero Banner + KPI Overlap
- Banner height: 200px
- Status cards overlap via negative margin: `-mt-12`
- Banner image: `object-cover` with `object-position: center 25%` (show the top/skyline, not center)
- Cards use `backdrop-blur-sm` and `bg-card/95` for glass effect over the banner

### KPI Card Sizing
- KPI 1 (System Status) and KPI 4 (Network): **wider** — `1.3fr`
- KPI 2 (Infrastructure) and KPI 3 (Security): **standard** — `1fr`
- Grid: `grid-cols-[1.3fr_1fr_1fr_1.3fr]`
- Cards have compact padding: `p-4` (not p-5 or p-6)

### No Footer
- The mockup does NOT have a footer/status bar
- Do not add one unless explicitly requested

### Target Display
- Primary design target: **16-inch screen / 1920px width**
- Lots of horizontal space available — don't constrain content width unnecessarily
- Design should feel spacious, not cramped

### Typography Sizes (smaller than default)
- Card titles: 10-11px, uppercase, tracking-[1.5px], secondary color, font-medium
- Large numbers: 24-28px, bold, primary color
- Subtitles/labels: 10-11px, secondary color
- Body text in lists: 13px, primary color
- Timestamps: 11px, secondary color
- Breakdowns: 9-10px, secondary color

### Animations
- Card hover: border → gold, 0.2s ease
- Progress ring: animates from 0 to value in 1s
- Sparklines: draw animation 1s
- Progress bars: fill animation 0.8s

### Icons
- Source: Lucide React (imported per component, tree-shaken)
- Size: 14-18px depending on context
- Color: gold for active/accent, text-secondary for inactive
- Gold glow on active sidebar items: `shadow-[0_0_6px_rgba(200,164,52,0.5)]`
