/* John The Plumber — demo stylesheet (Wave 3, V0.4).
   Art direction: personal trade nameplate. A cropped J/P letterform monogram is the
   hero focal point, then an editorial two-column service spread, a narrow installation
   ribbon and a grounded address-and-call close. Bone ground, near-black ink, one enamel
   oxblood reserved for the call action and the stamped registration marks.
   No frameworks, no webfonts, no raster images. */
