   NorthByte · concept.css (conceptbalk)
   Overgenomen uit Northbyte/voorbeelden/gedeeld/conceptbalk.css. De vaste
   zwarte balk onderaan laat zien dat dit een conceptontwerp van NorthByte is
   voor H2O, en niet de echte site van H2O.

   - Vast onderaan (position: fixed), dus geen layout-sprong. De ruimte die de
     balk inneemt staat vanaf de eerste paint als padding op <body>.
   - Gebruik var(--nb-balk-h) voor eigen vaste knoppen onderaan, bijvoorbeeld:
     bottom: calc(var(--nb-balk-h) + 12px);
   - Op mobiel is de balk ingeklapt (48 px); de knop Meer schuift een paneel
     omhoog. Alleen transform en opacity bewegen.
   - Alles begint met .nb- zodat het nooit botst met de CSS van de conceptsite.
