📚 Description

Recorded results sit too far below the homepage pitch, and mobile demo pages put navigation ahead of the selected output. Show a balanced hero with a manual six-demo carousel, randomize its starting order and homepage trending rows per visit, and keep each Skill's original rank. The hero shows the output, author, and a minimal Open the demo link.

Selected demo pages size interactive frames against screen height and keep the author and actions in a sticky bottom row. Prompt, model, effort, and recorded token usage share one compact header. Prompt expands to show the task and exact input, output, and cached input counts. Missing usage stays absent. Films retain their aspect ratio. Their actions copy the Skill link with the recorded task, offer the terminal command, and share the selected demo page. Mobile demo pages lead with the output and hide Run. Anonymous demo counts record exposures, successful copies, fixed campaign labels, and coarse elapsed buckets while preserving existing command copy totals.

Checked by the Agent against production after merge commit 5a9beb3:

• The homepage hero has no model header, prompt, Run action, or share button. Next demo changes the carousel from 1 of 6 to 2 of 6.
• Open the demo navigates to the displayed Skill's exact demo route.
• On a 390 × 844 screen, the selected HTML frame is 574px tall. The author/actions row ends at the viewport bottom. Run is hidden and no horizontal overflow appears.
• Prompt opens with keyboard Enter. It shows medium effort and exact input, cached input, and output counts.
• Share and Agent prompt actions show their successful copy states. The Agent prompt includes the Skill link and recorded task.
• The production route smoke contract passes after rollout.
