   Bruenn Plumbing — stylesheet
   Class names follow CSS Class Naming Convention v1.2:
   - Sections are .sect + a combo (.sect.sect-hero)
   - Containers are .wide / .skinny and set max-width only
   - Grids are .grid-[cols]-[name], flex is .flex-[name]; neither sets display
   - Webflow-managed classes (.w-container, .w-layout-grid, .w-layout-hflex,
     .w-layout-vflex) supply display and auto margins, mirroring Webflow
   - Cards are .card-[name]; utilities are single-property (.bot20, .p-lg)
