/* Sapuna Product Finder – mobile-first styles.
 *
 * Palette: the --sapuna-* design tokens defined on sapuna.uk.
 * A complementary scheme – cool teal/mint family (hue ~165–181°) balanced
 * by a warm sand/cream family (~32°) – applied roughly 60/30/10:
 * cream background, white cards with mint borders, teal and sand accents.
 *
 * Brand teal (#57ADAE) is only 2.6:1 against white, so it is used for
 * fills, borders and dark-on-teal elements. Text and white-on-colour
 * elements use --teal-text, a darker step of the site's deep teal (#2F7D6D).
