# Apex Track Experience — Vehicle Registration Snippet

## Build Pattern

A self-contained HTML/JS snippet for vehicle registration with cascading dropdowns (Make → Model → Year → Color → Specs), hosted on WordPress via Elementor HTML widget.

## Architecture

- **Static JSON dataset** — make/model/year/horsepower in a single `vehicles.json` file. No API calls, no recurring cost.
- **Inline all-in-one HTML** — the snippet contains styles, vehicle data, JS logic, and dark/light theme. No external dependencies. Single copy-paste deployment.
- **Cascading dropdowns** — Make selects populate Model, Model populates Year, Year enables Color. Each step is disabled until the previous is selected.
- **Specs remain locked** until all fields (including Color) are filled — the Horsepower panel only appears after the user picks a color.
- **Color field** — 16 preset options + "Other" with free-text input. Triggers specs display on selection.

## Themes

Two versions exist:
- **Dark theme** — `apex-register.html` at the portal mockup. Black background, orange accent.
- **Light theme** — `apex-vreg-final.html` sent to user. White background, blue accent, matching WordPress light themes.

## Deployment

Paste the entire content into an Elementor `HTML` widget on the target page. No additional configuration needed — vehicle data embedded as a JS object literal.

## Adding Vehicles

Edit the `vData` JSON object inside the `<script>` tag. Structure:
```json
{"Make Name": {"Model Name": {"2024": 500, "2025": 520}}}
```

Make/Model sorted alphabetically. Years sorted descending (newest first).

## Vehicle Data Source

Compiled from manufacturer spec sheets for exotics/performance cars (Ferrari, Lamborghini, Porsche, McLaren, etc.). The `exotic-vehicle-scout` cron job checks daily for newly announced models.

## Building a New Snippet

1. Compile vehicle data as JSON
2. Choose dark or light theme
3. Build HTML with Tailwind CDN or inline styles
4. Use `{VEHICLE_DATA}` as placeholder, inject real JSON at build time
5. Email as file attachment (16KB+ — too large for email preview)
