   Teletext Base Styles
   ========================================================================== */

/*
 * The teletext look relies on a strict monospace grid with no anti-aliasing,
 * sharp pixel edges, and the classic black background with bright primary colors.
 * We enforce 40-column-ish layout through max-width and character sizing.
