/* ============================================================
   Application detail page — section layout
   Continues the solution detail page's grammar: a hero with the
   record picture and tags, alternating white / soft sections,
   cards with a 3px top edge, numbered flow steps, label/value
   rows in framed panels, and a blue closing band with the
   numbered checklist. Colours and type come from tokens.css;
   .eyebrow, .section-heading, .nz-chip, .nz-card, .text-link and
   the .nz-spec renderer are global. Local prefix: nz-app-.
