The cookbook's 'Try it live' iframe is 600px tall, but the demo page
included its own h1/subtitle + ~32px main padding + the chat section had
minHeight:520, which pushed total content past 600px and forced a
scrollbar inside the iframe.
The shell-docs cookbook page already provides a header and surrounding
chrome; the demo's own h1 ('CopilotKit x Daytona') and subtitle are
redundant in the embedded context. Drop them and let the chat fill the
iframe viewport exactly:
- Remove the <header> (h1 + subtitle).
- Set <main> to height:100vh, padding:0, margin:0.
- Chat <section> uses flex:1 + minHeight:0 (no fixed minHeight) so it
grows/shrinks to fill the available iframe height.
Side effect: the standalone Railway URL now also shows just the chat
(no h1/subtitle). Fine — the URL is a demo embedding target rather
than a polished standalone landing.

CI's check-config-allowlist failed on the new daytona-runcode showcase.
Rather than just adding an .mjs row, convert to .ts to match the
dominant pattern across examples/showcases/* (the .mjs predates the
Next 14 TS-config support and is only kept in a handful of older
showcases — banking, enterprise-brex, orca, presentation). New
showcases should follow the .ts convention.
- Replace examples/showcases/daytona-runcode/next.config.mjs with an
equivalent next.config.ts (empty config, same behavior).
- Add the new path to .github/config-allowlist.txt in alphabetical
position (between chatkit-studio/.../world and deep-agents-finance-erp).
- Verified locally: bash .github/scripts/check-config-allowlist.sh passes.

Addresses PR #5087 review comment from @tylerslaton:
> Remove the blue padding around the chat, change the header to
> 'CopilotKit x Daytona'
- Drop the linear-gradient(160deg,#f8fafc,#eef2ff) background from
<main>. The chat's own white card now stands on the default page
background — no surrounding tint.
- Change the h1 from 'CopilotKit × Daytona' (× = U+00D7
multiplication sign) to literal 'CopilotKit x Daytona' (ASCII x), per
Tyler's literal request.

Reviewer asked to emphasize the runCode tool more, so:
- Replace CopilotSidebar with a centered CopilotChat (the chat is now the
focal point of the page rather than a docked side panel).
- Increase the renderer's code pane to ~12 lines (was ~6) so multi-line
generated code is visible without scrolling.
- Add 'Generated code:' label above the code pane to match the 'Result:'
label below.
- Configure starter suggestion pills via useConfigureSuggestions with
descriptive titles ('Python — Zoo animals', 'TypeScript — Fibonacci
numbers', 'JavaScript — Current timestamp') and available: 'always' so
they persist across iterations rather than disappearing after the first
message.
- Wrap the chat in CopilotChatConfigurationProvider to replace the default
'How can I help you today?' welcome text with something on-topic
('Ready to run code in a Daytona sandbox. Try a starter below, or
describe what you'd like to execute.').
- Tighten the BuiltInAgent system prompt so the agent does not restate
stdout in chat text — the renderer card already shows it.

The deployable Next.js demo behind the new Daytona cookbook recipe. A minimal
CopilotKit Built-in Agent whose only added capability is the recipe's runCode
server tool — executes Python / TypeScript / JavaScript in an isolated Daytona
sandbox and streams the result back to the chat via a custom useRenderTool
card (fixed-height streaming code pane with react-syntax-highlighter +
vscDarkPlus, mirroring @copilotkit/react-ui's own CodeBlock, and a fixed-
height result pane with a 'Generated code:' / 'Result:' label pair). The
agent's system prompt instructs it not to restate stdout in chat text since
the renderer already shows it.
Standalone npm project — intentionally not in the monorepo's pnpm workspace
(matches the existing examples/showcases/* convention; only generative-ui-
playground is in the workspace globs). Validated end to end against published
@copilotkit/runtime@1.58.0 with both Python and JavaScript snippets round-
tripping through real Daytona sandboxes.
