   CLOSE — owned by Agent CLOSE. The page floods: paper-2 → flood → abyss.
   Scope every rule under .close

   .close            paper-2 ground (so the flood has something to rise over)
     .close-foam     pale band that leads the flood wave        (.is-tide only)
     .close-water    flood field, clipped by wave A             → #contact
       .close-end
         .close-deep deep-blue band that leads the abyss wave   (.is-tide only)
         footer      abyss field, clipped by wave B             → wordmark + footer

   Without JS the two fields use the foundation's static .crest edge. js/close.js
   adds .is-tide, hides those, and clips each field with a wave that rises with scroll.
