   North Focus — Problems · Final Direction
   Builds on site.css + DS tokens. One coherent page, one dominant visual idea:

       A sensible response becomes a foundation that more and more work
       quietly comes to rest on.   response → repetition → dependency → weight

   The load-on-a-coral-foundation motif appears twice — fully in "How it builds"
   and again, growing over time, in "Why act now" — so the page has a single
   visual spine rather than several competing metaphors.

   Colour rhythm (the established two-navy bracket):
       Hero            paper      — recognition, non-blame
       Signals         NAVY       — the densest recognition beat
       How it builds   paper      — the causal spine + load stack
       Lived reality   paper      — Andrew has been the workaround (portrait)
       Why act now     paper      — the load gets heavier each year
       The hard part   paper      — judgement shown through four questions
       Close           NAVY       — collaborative next step
