 * Direction: a trustworthy "modern vet-meets-DTC pet brand" look for a North
 * American audience. Deep pine green reads natural/healthy without the
 * overused cream+serif+terracotta cliché; warm honey is the single accent
 * (the colour of kibble). Signature device: monospace numerals for prices and
 * nutrition data, so the *data itself* carries the personality and signals
 * precision/trust. Spend boldness on the price-per-kg metric; keep the rest quiet.
