/* ============================================================================
   Martomato landing — styles.css
   Redesign 2026-06-12. Vanilla CSS, no preprocessor, no build step, no
   webfonts (system stacks only — first paint is instant on shared hosting).

   COMPONENT VOCABULARY (matches class names; reuse these, don't fork):
     .wrap        — 1120px content column
     .kicker      — numbered uppercase section eyebrow ("01 · The data path")
     .cta / .cta-ghost — primary / outline action
     .status-pill — live project-status chip
     .sec / .dkz  — section band; .dkz = dark zone (hero, canvas, SDK, closing)
     .zc-*        — zero-copy data-path diagram (the page's centrepiece)
     .jnode/.jchip— journey node: colour token (--nc) + BPMN shape class
                    (.s-event circle · .s-gate diamond · .s-task rounded square
                     · .s-goal ringed circle) — mirrors app/shell.css exactly
     .canvas-*    — static journey-canvas figure (dot grid + nodes + SVG edges)
     .capgrid     — spec-sheet capabilities grid (mono indices)
     .spec        — key/value spec table (SDK section)
     .seclist     — security & compliance rows
     .roadmap-*   — milestone timeline
     .faq-*       — details/summary accordion

   THEME MODEL: two zones. Light zones read from the semantic tokens below;
   dark zones (.dkz) re-point the SAME tokens, so every component works in
   both. prefers-color-scheme: dark re-points the light zone too — the page
   becomes all-dark with .dkz bands kept a step warmer for rhythm.
