/*
 * ABN App Shell — shared styles
 * -----------------------------------------------------------
 * Canonical styles for chrome elements that should be identical
 * across all web apps: back button, feature request button + dialog,
 * wordmark logo, app title, common animations, common dialog modal.
 *
 * Load AFTER any app-specific :root variable block.
 * Expected CSS variables (both shotlist and calendar define these):
 *   --bg, --surface, --border, --border-strong
 *   --text, --text-secondary, --text-muted
 * -----------------------------------------------------------
