Mobile Warning: Code Block Horizontal Overflow

All 4 mobile viewports (360–428px wide) show a code block overflow issue on the landing page:

• The Expressive Code YAML workflow example block contains lines whose rendered width reaches ~554px (white-space: pre)
• body.scrollWidth (554px) exceeds body.clientWidth (344–412px) on all mobile viewports
• body, html { overflow-x: hidden } clips the overflow — no horizontal scrollbar appears, so mobile users cannot scroll to see truncated content
• The <pre> element has overflow-x: auto via EC CSS, but the body-level hidden overflow suppresses this at narrow viewports
• Breakpoint: overflow resolves at ~600px viewport width (550px overflows, 600px does not)

Recommendations

1. Fix mobile code block overflow — The landing page YAML example is clipped on all mobile viewports < ~560px. Options:
   • Add overflow-x: auto (not hidden) on the code block's container at mobile breakpoints, or
   • Shorten the longest YAML lines in the example to fit within ~360px rendered width, or
   • Add a media query to allow horizontal scroll within the code block wrapper while keeping page-level overflow hidden
