Accessibility & keyboard use

Spark Tray is built to be usable by keyboard and with assistive technology.

• Full keyboard navigation: move between controls with Tab / Shift+Tab, and activate buttons and switches with Enter or Space. Focused controls show a clear focus outline.
• Screen-reader friendly: screens, sections, progress bars, and status indicators are labeled, and live regions announce job progress and the current exchange status.
• Search everywhere it helps: the Settings screen has a search box to jump straight to any preference.
• Readable status: job statuses and the bandwidth-exchange state use both text labels and color, so meaning isn't conveyed by color alone.
