   Scoped to body.page-periodontal-disease. Page hero, sec-head, stick, rich, ledger, points, accordion and related are shared (site.css).
   Two drawings. The stages (ink): two molars in cross-section, gingivitis then periodontitis, ported from the retired
   /gum-diseases/ page (classes stg-*). The diagnosis plate: the teeth seen from above, set in their gums; a scale runs
   it from gingivitis to periodontitis as the gums swell, deep pockets open in the accent colour and the bone (dotted)
   draws back (classes pdz-plate, pdz-tooth, pdz-ann…). */
