/**
 * Retro Footer — Base Styles (structure only)
 *
 * "The Receipt": a torn-edge paper receipt, centered, dropped on the store
 * floor at a slight angle with a strip of tape at the top. Inside, the store
 * header sits over a stack of printed line-items (the sections), a stamped
 * socials row, and a barcode + credit at the bottom.
 *
 * Structure:
 *   .retro-footer            – section, the store floor
 *   .retro-footer__receipt   – the tilted receipt wrapper (carries shadow/tape)
 *     .retro-footer__edge    – torn paper edges (top + bottom)
 *     .retro-footer__paper   – the printed surface (padding lives here)
 *
 * All color, texture, torn-edge shape and shadow treatment live in styles/*.css.
