/* Lunomi portal. Taste Skill "framed sheet" app style: one tinted L-frame (sidebar + top bar) and the work on a
   white sheet inset 8px, hairline edges, no shadows. Brand: Tiffany blue on white and black, flat colour only, as on
   the home page. The blue (--brand) goes on the mark, data (chart bars, credit runway), the selected nav item and the
   sign-in ground; a deep teal (--accent) carries accent text and focus, because the blue is too pale for text.
   Grid: canvas padding 24, one gap of 24 both ways; two-up rows = 2 × 1fr + 24; main rows = 2fr + 1fr + 24.
   Type scale: 12 / 14 / 16 / 22 (title) / 26 (KPI) / 32 (the one answer figure). Weights 400 / 500 / 600. */
