/*
 * shared/base.css — the "Fight Night" look shared by the host screen and phones.
 *
 * Idea: every matchup is a boxing poster. Red corner vs. blue corner,
 * cream "paper" cards with thick ink outlines and hard offset shadows,
 * a gold accent, and halftone dots like old printed posters.
 *
 * Fonts (loaded from Google Fonts in each HTML file):
 *   Bungee              → chunky marquee display type (titles, codes, numbers)
 *   Bricolage Grotesque → characterful but very readable text (prompts, answers)
