/* dreamdata.nz shared site style.
   One stylesheet for every dreamdata.nz page (starter page, ICP map, NZ generation, and the Dash energy
   dashboard, which loads it from its assets/ folder). Page-specific layout stays in each page.
   Brand colours: navy #0F1B2D, teal #2BB5A3, amber #F2A93B, grey #9FB0C3 (see BRAND_README.md).
   Contrast: white text on the brand teal is too faint (2.6:1), so selected buttons use navy text on teal
   (6.8:1) and text links on light backgrounds use a darker teal, #1A7F72 (4.9:1). */
