/* Duit website: the content sections (SPEC 7.2, 7.4, 7.7-7.12). Owner: sections.
   Needs site.css (tokens, .wrap .sec .sec-head .eyebrow .lede, buttons, .g glyphs). Every rule here is scoped
   to one section's own class prefix, and styled by token only (grounds nest).

   hero-*  hero copy, a fragment inside the shell's .hero: .hero-copy > .hero-eyebrow, h1 (.hero-l lines),
           .hero-side > .hero-sub + .hero-cta. Two columns from 1200px (headline left, sub and buttons right).
   say-*   #about: big statement lines (.say-line, trailing .say-soft clause). Optional scroll fade, CSS only.
   uc-*    #why: three use cases split by 1px rules; each ends in a text illustration (.uc-ill, glyph rows).
   tr-*    #trades: eight trades in a ruled grid (.tr-grid > .tr-cell), a darker cream band.
   ag-*    #any-agent (sky): the round table (.ag-table: rim + spokes svg, .ag-board, .ag-seat .ag-s1-5)
           and the four layers (.ag-stack > .ag-layer, .ag-what role line, .is-duit .is-top/.is-bottom joined,
           .ag-tag legend).
   da-*    #data: h2 in two set lines (.da-l), platform chips in four groups (.da-groups), then the two
           storage cards (.da-store).
   co-*    #consulting: copy + CTA left, "What we handle" glyph list right, a darker cream band.
   ct-*    #contact (sky): copy and next steps left, the form right.
   cf-*    the contact form (js/contact.js): .cf-field .cf-pair .cf-select .cf-err .cf-trap .cf-send
           .cf-status (.is-ok / .is-bad) .cf-note. */
