/* AeroLink — shared styles (redesign "Le Colis", October 2026).
 *
 * The parcel is the hero. Bold flat colour fields sit inside a white page,
 * and oversized drawn kraft boxes, wrapped in one band of sky tape, tumble
 * through those fields, always half cropped by the field's edge. The price
 * panel is a crisp white card sitting on the field. Every section below
 * changes composition: the four steps are four objects, the zones are
 * stamped hub names, the business block is a stack of boxes in the corner
 * of a navy field. Playful but precise. Never a warehouse, never people.
 *
 * Amber (#F5A524) is reserved for the one action per screen view and the
 * calculator's title. Light mode keeps a white page; dark mode is navy, but
 * the sky field and the parcels keep their colours (owner's decision).
 * Typography: docs/design/typography.md (Montserrat 700 for display,
 * Manrope for text, tabular figures).
 *
 * Shared here: tokens, bands (the colour fields), objects (the parcels),
 * cards, header, buttons, forms, tiles, stamps, steps, footer, tab bar,
 * quote bar, help chat, motion. Each page has its own stylesheet beside it. */
