   Motif   : confidence gauge (semi-circle dial sweeping to "full" — new, distinct signature)
   Template pattern: tabbed problem/solution/results block, accordion ingredient list,
              comparison table (vs. traditional routines) — none of these existed in
              the previous two KlaroNail builds
   Rules   : img max-width min(Npx,100%) · mobile hero image renders before H1
