/* Risorra Tools — utility-site skin.
   Same palette tokens as risorra.com (styles-v2.css) so the two properties
   read as one family, but a system font stack instead of the self-hosted
   Fraunces/Inter set: this is a utility people arrive at from search, use
   once and leave, and webfont bytes buy nothing here.
   ponytail: the display voice is borrowed from the parent's Fraunces by
   using the system serif for headings — same editorial feel, zero requests.
   Swap --font-display to Fraunces if the two sites ever share a font cache. */
