/*
 * ==========================================================
 *  styles.css — every colour, size and shape in the app
 * ----------------------------------------------------------
 *  Look & feel: calm, solid colours, clear type, thin lines —
 *  like a well-printed bill. No gradients, no glass effects.
 *
 *   1. Colour tokens  – light (white + green) on :root,
 *                       dark (black + white + soft green) on
 *                       [data-theme="dark"]. Change colours here.
 *   2. Base, header, step bar
 *   3. Building blocks: panels, buttons, inputs, choices
 *   4. Each screen: start, price, appliances, budget, result
 *   5. Drawings: meter disc, Bijli, bill paper, rating sticker
 *   7. Bill slip (PDF download / print)
 *   6. Keyframes (small loops only) + reduced motion
 *
 *  Mobile first: base styles are for phones (320px+);
 *  @media blocks add room on bigger screens.
