  # Initial Schema Setup

  1. New Tables
    - `profiles`
      - `id` (uuid, references auth.users)
      - `username` (text, unique)
      - `theme_color` (text, enum)
      - `created_at` (timestamptz)
      - `updated_at` (timestamptz)
    - `collections`
      - `id` (uuid)
      - `user_id` (uuid, references profiles)
      - `card_id` (text)
      - `quantity` (integer)
      - `created_at` (timestamptz)
      - `updated_at` (timestamptz)
    - `decks`
      - `id` (uuid)
      - `user_id` (uuid, references profiles)
      - `name` (text)
      - `format` (text)
      - `created_at` (timestamptz)
      - `updated_at` (timestamptz)
    - `deck_cards`
      - `id` (uuid)
      - `deck_id` (uuid, references decks)
      - `card_id` (text)
      - `quantity` (integer)
      - `is_commander` (boolean)

  2. Security
    - Enable RLS on all tables
    - Add policies for authenticated users to manage their own data
