This PR updates the "thinking" state of the docs assistant widget so it shows an animated icon next to the three dots while the bot is looking up and writing an answer.
What changed:
docs/js/docs-assistant.js— the placeholder that used to be a static…is now a bubble containing:It also gets
role="status"andaria-label="Searching the docs and writing an answer"so screen readers announce the working state. The error fallback still works (it overwrites the bubble with the text message).material-overrides/assets/stylesheets/docs-assistant.css— added theda-spark(icon) andda-bounce(dots) keyframe animations, laid the indicator out in a flex row, and included aprefers-reduced-motionguard so the animation is disabled for users who opt out.The icon uses the existing theme variables (
--accent-default,--color-text-secondary), so it follows light/dark mode automatically like the rest of the widget. I verified it renders correctly in the browser.
