/* Product Speedrun showcase pages: the shared series look.
 *
 * Every episode's 6-showcase/index.html links this file (../../../kit/showcase.css) and sets only
 * its own accent colours, in a <style> block after it:
 *
 *   :root { --accent: #2fbf5b; --accent-ink: #157a36; --accent-soft: #e3f6e9; }
 *   @media (prefers-color-scheme: dark) { :root { --accent-ink: #6ff09a; --accent-soft: #15301f; } }
 *
 * Layout, type, spacing and components come from here, so episodes read as one series.
 * Start a page from kit/showcase/template.html; kit/showcase/README.md lists the parts.
