+# JUNOHUB Logo Specification
+
+Simple, minimalist logo spec aligned with product and existing site branding. Use this for asset production (PNG, SVG) and design handoff.
+
+---
+
+## 1. Product context
+
+- **Product name:** JUNOHUB  
+- **Tagline:** “The Unified Supply Chain Hub” / “Modern Commerce Infrastructure”  
+- **Use:** Vendor and supplier portal, dropshipping, encrypted commerce (Gmail, Shopify, etc.).  
+- **Tone:** Modern, high-performance, trustworthy, minimal.
+
+---
+
+## 2. Logo description (for designers / AI)
+
+**Overall:**  
+A minimal logo for a B2B supply-chain and commerce platform. Clean, geometric, no decorative detail. No tagline inside the logo.
+
+**Icon (mark) — product-based recommendation:**  
+- **Concept:** The icon should reflect **JUNOHUB as a hub** — the single place where vendors, suppliers, and stores connect. Prefer a **hub / connectivity** idea over a generic symbol.  
+- **Recommended direction:** A **central node with connections** — e.g. one central dot or shape with two or three short lines or smaller nodes linking to it (suggesting “unified” and “supply chain hub”). Keep it geometric and minimal: no literal boxes, trucks, or globes.  
+- **Alternative:** **Connected nodes** — e.g. three small circles or diamonds in a tight network (one central, two flanking), implying vendors and suppliers meeting at one platform.  
+- Simple, bold strokes; must read clearly at 24×24px.  
+- Placed inside a **rounded square** (soft corners, not a circle).  
+- Icon is the only graphic element; no extra decorative shapes.  
+
+*Note: The app currently uses a lightning bolt (Zap) as a placeholder; the above is the recommended product-aligned mark for the FYP / final branding.*
+
+**Wordmark:**  
+- The word **“JUNOHUB”** in all caps.  
+- Sans-serif, heavy weight (e.g. Black or Extra Bold).  
+- Tight letter-spacing (slightly negative tracking).  
+- No underline, no gradient on the wordmark in the primary lockup.
+
+**Lockup:**  
+- Icon and wordmark sit side by side with a small, fixed gap.  
+- Icon left, wordmark right.  
+- Can be used as icon-only (e.g. favicon, app icon) or icon + wordmark (navbar, footer, docs).
+
+**Style:**  
+- Flat, no 3D or skeuomorphism.  
+- No gradients in the icon for the primary version (solid fill).  
+- Optional: a secondary version with a subtle top-left to bottom-right indigo gradient for the icon only, to match the website’s gradient treatment.
+
+---
+
+## 3. Color scheme (match the website)
+
+Use these exact values so the logo matches the app and marketing site.
+
+| Role            | Hex       | Usage                                      |
+|-----------------|-----------|--------------------------------------------|
+| **Primary**     | `#4F46E5`| Icon background (primary logo)             |
+| **Primary alt** | `#6366F1`| Optional gradient end (indigo-500)         |
+| **Lighter**     | `#818CF8`| Optional gradient end (indigo-400)         |
+| **Icon/on-dark**| `#FFFFFF`| Symbol and wordmark on dark UI             |
+| **On light**    | `#020617`| Wordmark on light backgrounds (light mode) |
+| **Background**  | `#0A0E1A`| App background (dark); use for contrast     |
+
+**Primary logo (dark backgrounds):**  
+- Icon: rounded square fill `#4F46E5`, symbol (hub mark) `#FFFFFF`.  
+- Wordmark: `#FFFFFF`.
+
+**Light / alternate (light backgrounds):**  
+- Icon: rounded square fill `#4F46E5` (or very light indigo `#EEF2FF` with symbol `#4F46E5`).  
+- Wordmark: `#020617`.
+
+Keep the logo color scheme limited to this indigo + white/dark set; no extra accent colors in the mark or wordmark.
+
+---
+
+## 4. Dimensions and resolution
+
+### Icon (mark only)
+
+| Asset            | Size (px) | Format | Use case                          |
+|------------------|-----------|--------|-----------------------------------|
+| Favicon          | 32 × 32   | PNG/SVG| Browser tab, bookmarks             |
+| PWA icon         | 192 × 192 | PNG    | Android / PWA (manifest)          |
+| PWA icon         | 512 × 512 | PNG    | High-res PWA, splash               |
+| Apple touch      | 180 × 180 | PNG    | iOS home screen (manifest)        |
+| Navbar/sidebar   | 40 × 40   | —      | In-app (can be SVG or 2x PNG 80×80)|
+| Marketing        | 48 × 48+  | SVG/PNG| Landing, footer, social, docs      |
+
+**Recommended:**  
+- Export SVG for icon (scalable).  
+- Export PNG at **1x and 2x** for 32, 192, 512, and 180 where needed.  
+- Minimum clear space: ~1/4 of icon height on all sides.
+
+### Full logo (icon + wordmark)
+
+| Context   | Icon size | Notes                          |
+|-----------|-----------|---------------------------------|
+| Navbar    | 40 × 40   | Icon + “JUNOHUB” wordmark       |
+| Footer    | 40 × 40   | Same lockup                     |
+| Marketing | 48 × 48+  | Scale wordmark with icon ratio  |
+
+**Aspect ratio:**  
+- Icon: 1∶1.  
+- Lockup: define one preferred width (e.g. icon 40px) and keep proportion for “JUNOHUB” (e.g. ~20–24px cap height).
+
+### Resolution rules
+
+- **Raster (PNG):** 72 ppi for web; 144 ppi acceptable for 2x assets.  
+- **Minimum size:** Icon should read clearly down to 24×24px; avoid thin strokes below 2px.  
+- **Safe zone:** Do not crop into the rounded square; keep padding so the shape is fully visible.
+
+---
+
+## 5. File naming (reference)
+
+- `icon.svg` — Icon only, scalable.  
+- `icon-192.png` — 192×192 PWA.  
+- `icon-512.png` — 512×512 PWA.  
+- `apple-icon.png` — 180×180 Apple touch.  
+- `logo.svg` — Full lockup (icon + wordmark).  
+- `logo-dark-bg.svg` / `logo-light-bg.svg` — Optional light/dark variants.
+
+---
+
+## 6. Do not
+
+- Add gradients to the wordmark.  
+- Use more than one accent color in the mark.  
+- Use a generic symbol (e.g. lightning, star) that does not relate to hub / supply chain / connectivity.  
+- Use thin or script type for “JUNOHUB”.  
+- Stretch or alter the rounded-square proportion (keep 1∶1).
+

+
+*Aligned with JUNOHUB app and landing (navbar, sidebar, footer, manifest, `globals.css`).*
