Rework color palette to sun yellow, forest green, nut brown

Client requested a sunflower-themed palette: forest green stays for
links/nav, nut brown for the secondary reorder button, and a new sun
yellow becomes the primary CTA color (with dark ink text for contrast).
Neutrals and status pills retuned to match, with a darker companion
palette for prefers-color-scheme: dark.
