/* VeriMemory — visual system.
 *
 * An editorial product surface, not a dashboard. The rules it holds itself to:
 *
 *   Paper, not chrome.      Warm off-white ground, hairline rules, no shadows
 *                           except where something genuinely floats above the
 *                           page (the drawer, a toast). Nothing glows.
 *   Type does the work.     A serif for headings, a sans for interface text.
 *                           Hierarchy comes from size, weight and space rather
 *                           than from boxes, badges or colour.
 *   Colour means something. Ink for text, one restrained green for verified,
 *                           one muted red for integrity failure. A reader who
 *                           sees colour is being told something specific.
 *   Square-ish surfaces.    2px radius. Rounded cards read as consumer app;
 *                           hard corners read as record.
 *
 * Committed to a single light palette. The brief specifies warm cream, and a
 * dark variant of an editorial paper surface would be a different design rather
 * than the same one inverted — so `color-scheme` is declared light, which keeps
 * form controls and scrollbars in step instead of leaving them to the host.
