/* How it works (redesigned 2026-10-20 to the founder's mockup): a hero with the lifecycle diagram (bring data,
   your LakehouseBox, connect tools; you choose where compute runs) and the structure strip; the admins' four steps;
   the tools grid; the capabilities as vertical tabs (how-it-works.js; without script every panel shows); where it
   fits (the comparison, folded); the closing call. Icons carry their size and colour in the markup. */
