   peptidebio — theme stylesheet
   Written for this store. No third-party theme code.

   Everything the pages share lives here, in one cached file, so a section
   only ever emits the handful of declarations that depend on its own
   settings. Sections are addressed by class, never by element, so markup can
   change without chasing selectors.
