EmptyState.css

/*
 * Shared empty-state surface
 * ----------------------------------------------------------------------------
 * Used by `<EmptyState />` and any direct consumer that still lays out an
 * `<div class="empty-state">` block (TransactionHistory, CreditLines).
 *
 * NOTE: Some legacy consumers (TransactionHistory.css, Dashboard.css) ship
 * a duplicated subset of these rules. That duplication is intentional for
 * now — pulling them into this file would touch unrelated pages. Keep the
 * two copies in sync if you change a shared property (radius, focus ring,
 * accent tint).
 *
 * Layout: vertically centered column with generous vertical padding, an
 * illustration on top, optional eyebrow, a heading, descriptive copy, and an
 * action row. The component itself owns focus/aria concerns; this file is
 * purely presentational.
 *
 * Theming: all colors reference design tokens declared in src/index.css so
 * the empty state responds to the active theme (default / high-contrast).
