/* Hand-written CSS so the project has no frontend build step.

 * COLOURS LIVE HERE. Every colour in the app comes from the variables below —
 * nothing else hardcodes one — so changing the look means editing this block,
 * or better, not editing anything at all:
 *
 *   APP_THEME=purple              in .env, picks one of the themes below
 *   APP_ACCENT_COLOR=#0f766e      in .env, sets any accent colour you like
 *
 * See config/theme.py. Keep the accent dark enough that white button text
 * stays readable (4.5:1 contrast or better).
