💡 What: Improved the accessible loading states on generic Buttons (src/components/ui/button.tsx) by using an overlay technique. Instead of entirely replacing the button's content with a spinner, the original content is now rendered but visually hidden using opacity-0 (to maintain button width and prevent layout shift). The spinner is positioned absolutely over the center of the button, and a screen-reader-only .sr-only span text "Loading" is added. Additionally, the standard aria-busy attribute correctly informs screen readers about the async operation.
🎯 Why: Generic buttons across the application often lacked proper accessible loading states. A user utilizing a screen reader would not be informed that an action is processing, and visual users would experience layout jiggling as text disappeared and was replaced by a spinner.
♿ Accessibility:

  • Added aria-busy="true"
  • Added <span className="sr-only">Loading</span>
  • Reduced unexpected layout shifts

Also recorded learning into .Jules/palette.md.
