/* Production Preview - Screen 1 (ruled-notepad Mad Lib) + app chrome.
   Ported from the approved design preview
   (out/claude_ref/preview_a2_homepage_fullscreen.html):
   - --rule 44px desktop / 36px mobile; rule line at the BOTTOM of each row
   - every line-height is 1 rule (or 1/2 rule for body text); all block gaps
     are whole rules; half-rule blocks sit in .rounds wrappers that the grid
     engine (app.js) rounds UP to full-rule multiples - STRUCTURAL grid
     safety, no hardcoded line-count compensation
   - content column max-width 860px, centered; paper spans the viewport */
