/* TariffSnap app styles — BlackBooks Lite visual language.
 *
 * Every colour, size, space and radius resolves to a token from
 * issaabuu-theme.css, which is a port of the BlackBooks Lite palette. Nothing
 * here invents a value. A buyer who has seen one Issaabuu product should not
 * have to be told this is the same company.
 *
 * The moves that make the family recognisable, in order of how much they carry:
 *   1. Warm parchment behind cream cards -- never a cold white page, and never
 *      a filled brand-colour banner across the top.
 *   2. A serif display face for titles and amounts, over a humanist body face.
 *      Card section headers are italic; nothing else is.
 *   3. An uppercase, letterspaced gold micro-label above a section.
 *   4. Generous card radii with a soft, warm shadow.
 *   5. A semantic figure sits on a pale wash of its own hue.
 *
 * What this replaced: Arial, a Material-palette blue belonging to no Issaabuu
 * surface, and text-align: center on body.
