### /login
Supabase Auth login page (email + password, or magic link).

Supabase Auth signup page → auto-creates user profile (trigger from Feature 1.4).

### /blog
MDX-powered blog for SEO content. Static generation at build time.

**Implementation:**

- Each post: frontmatter (title, date, slug, description, tags) + MDX body
- `/blog` index page with post list, sorted by date
- `/blog/[slug]` dynamic route for individual posts
- SEO: Open Graph tags, JSON-LD structured data, sitemap.xml
- Reading time estimate in post header

**Blog post frontmatter:**
```mdx

## VYNDR Voice Guide
All user-facing copy follows these rules:
- **Direct.** No hedging. "This line is soft" not "This line might be worth considering."
- **Confident.** The system did the work. Present findings with authority.
- **Concise.** Bettors scan fast. Short sentences. No filler.
- **Respectful.** Never condescending. Assume the reader knows the game.
- **Honest.** If the edge is thin, say so. A D grade is "no edge — avoid" not "proceed with caution."

Examples:
- Hero: "Stop guessing. Start grading."
- Grade A: "Strong edge. Clear play."
- Grade D: "No edge. Walk away."
- Kill condition: "Back-to-back game. High-minute player. Historically underperforms."
- Upgrade pitch: "You've got a good eye. Unlock unlimited scans."
