/*
 * Talk With Jamie v2 stylesheet.
 *
 * A quiet messaging layout: cool grey-blue surfaces, one slate-blue
 * accent for the user's side of the conversation, small radii and
 * hairline borders. Both themes come from the custom properties
 * below, so components never restyle themselves per theme.
 *
 * Contents:
 *   1. Tokens and themes
 *   2. Base elements
 *   3. Buttons, inputs and notices
 *   4. Chat shell
 *   5. Messages and composer
 *   6. Auth screen
 *   7. Admin and context views
