   olentra.css — Olentra marketing site design system
   ------------------------------------------------------------
   STANDALONE. This file ships to getolentra.com only. It shares
   nothing with the Olentra application at drugtestmanagement.com:
   no imports, no shared selectors, no shared filenames. The
   application's styles.css / chq-nav.css are untouched and must
   stay that way.

   Identity brief: premium operations software for a regulated
   industry. Precise, engineered, calm, expensive. Software first —
   nothing in the visual language depicts testing, medicine or
   government. The product and the copy carry the industry.

   Palette logic: graphite + bone + ONE copper signal. Copper reads
   industrial and precise rather than clinical, and deliberately
   avoids the generic blue-gradient SaaS register. Operational
   status colours are a SEPARATE, cooler family so a status dot can
   never be confused with a brand accent.

/* ---------- 6b. Showcase ----------------------------------
   An auto-advancing tour of what the application does. Chapters
   on the left, one product surface on the right that cross-fades
   between them.

   Two decisions worth knowing before editing:

   1. The panels are STACKED IN ONE GRID CELL (all grid-area 1/1)
      rather than absolutely positioned. The stage therefore sizes
      itself to the tallest panel and never jumps height mid-cycle,
      and no panel needs a hard-coded height.

   2. The progress bar is a CSS animation, not a JS timer. That is
      what makes pause-on-hover a one-line rule, and it means the
      advance is driven by `animationend` — so if a user prefers
      reduced motion and the animation never runs, the tour simply
      never auto-advances and stays manual. That is the intended
      behaviour, not a fallback.
