/* marketing.css — the shared dark-hero landing system for the SoftwareConvene marketing pages.
   Used by: software/index.html, classconvene/{index,features,extension,roadmap}.html,
            teamconvene/{home,features,roadmap}.html

   ⚠ NEVER load this alongside /software/detail.css. That file is the LIGHT document theme used by
     software/{apps,orgconvene,bizconvene}.html, and the two disagree on what the tokens mean:
     there --ink is the TEXT color, here --ink is the BACKGROUND. They also both define .wrap,
     .hero, .cta, .chip(s) with incompatible rules. A page links exactly one of the two.

   ⚠ NOT for bizconvene/home.html (its own light theme, shares no tokens) or beta/dpa.html
     (a legal page, deliberately left with its inline copy). Don't "finish the job" on either.

   Brand is picked with a body class — the same mechanism detail.css uses for body.biz/.org/.apps:
     body.cc  ClassConvene    green,  serif headings
     body.tc  TeamConvene     orange, condensed uppercase headings
     body.sc  SoftwareConvene amber,  heavy sans headings
   Anything that is art rather than vocabulary (starfields, blueprints, mockups, one-off panels)
   stays in the page's own <style> block. */
