/*
 * Global styles for the RadioAccess website.
 * The default colour scheme uses a deep blue gradient reminiscent of night radio.
 * High contrast mode flips backgrounds to black and text to white for users with
 * low vision. A large‑font mode increases text size across the site.  The
 * layout is responsive: the iframe adjusts to fill the available space below
 * the fixed header.
