/* ─────────────────────────────────────────────── solutions.bamya.co

   The AI building blocks portfolio, on top of panel.css. Every colour is a
   panel.css token, so the page stays in the one palette: teal (--you,
   --live) for what the parts do, violet (--them) for the business areas and
   for what arrives from outside, amber (--warn) only for what a check flags.

   Parts, in page order:

     the hero          a smaller headline (the line is long)
     the principles    one row of four between two rules (not a full panel)
     the blocks        the area filter, and the card front: the part's name,
                       the outcome, the business value, the proof, where it
                       fits, and Details when the catalogue has them
     combinations      three columns under a thick rule, with block tags
     the steps         panel.css .cards, plus a small step label
     the dialog        a block's details and its use cases, and the Show me
                       view: the diagram (drawn by solutions-diagram.js) and
                       the worked example document
