   ReviewLoop — design system
   ----------------------------------------------------------------------------
   Branding goal: a calm, trustworthy utility. Confident enough that a seller
   believes it works; restrained enough that it never feels like a marketing
   funnel. One accent colour (teal), generous spacing, honest microcopy.
   No external dependencies — works offline, renders identically anywhere.
