Typed form instead of a chat prompt. v16 used a single textarea + send button. v17 shows the schema: prompt, tone enum, signature. Generated from floom.yaml. Makes the contract visible.
Output on the right, not below, on desktop. Keeps inputs and result in one viewport. Stacks on mobile.
Zero creator affordances for non-owners. Owners see a small "Open in Studio" ribbon top-right only.
After-run state: copy, share, run again. Share link is floom.dev/r/run_a7f3.
"Use this from your own code" block is collapsed under the output on desktop — surfaces the curl + Install-in-Claude path so people don't have to hunt for it.
Install CTA band at the bottom, matching landing's green-accent CTA. Same copy everywhere: "Install in Claude".
