🎨 Palette: [UX improvement] Enhance discussion composer accessibility and feedback

[bobdivx]

💡 What

Added aria-labels and a visual loading state (spinner) to the discussion composer's send button, along with keyboard focus styling.

🎯 Why

To improve accessibility and user feedback during asynchronous message submissions.

♿ Accessibility

• Added aria-label to the textarea and send button.
• Replaced the text > with <span aria-hidden="true">&gt;</span> to avoid redundant screen reader announcements.
• Added focus-visible:ring classes to the send button to support keyboard navigation.
• Conditionally render a spinner while sending to provide clear visual feedback.

Code Review

This pull request improves the accessibility and user feedback of the chat composer. It adds a documentation entry in .jules/palette.md regarding loading states, adds an aria-label to the message textarea, and introduces a visual loading spinner, focus-visible styles, and static ARIA attributes to the send button. The review feedback suggests dynamically updating the send button's aria-label and title to "Envoi en cours…" when sending, and adding aria-busy={sending} to further enhance accessibility for screen readers.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.
For more details on the timeline and next steps, please review the Help Documentation.

To improve accessibility during asynchronous message submission, the button's aria-label and title should dynamically update to reflect the loading state (e.g., changing to 'Envoi en cours…'). Additionally, adding aria-busy={sending} informs assistive technologies that the button is currently in an active loading state.

Suggested change

	aria-label="Envoyer le message"
	title="Envoyer le message"
	aria-label={sending ? "Envoi en cours…" : "Envoyer le message"}
	title={sending ? "Envoi en cours…" : "Envoyer le message"}
	aria-busy={sending}
