/**
 * Top-right user widget. Refined for the Rubick generative-studio aesthetic.
 *
 * Collapsed pill:  [ 96 credits ]   [ E ]    (credits on the left, avatar on
 *                                              the right, no name visible)
 *
 * Expanded:
 *   - same pill (no shape change on open — kept rounded, no flattened edges)
 *   - dropdown appears BELOW with a small gap, smooth fade + slide-down
 *   - dropdown header shows full name + email (the identity info that's not
 *     in the pill anymore)
 *   - then the menu items: Buy credits / Settings / Mode / Sign out
 *
 * Animation strategy: the dropdown is always rendered in the DOM. CSS
 * controls visibility via opacity + transform + visibility, so the
 * open/close motion is one smooth transition instead of an
 * appear/disappear flicker.
 *
 * Inherits color + font tokens from theme.css. Requires theme.css to be
 * loaded before this file.
