Webduino Remote is a static, browser-run universal remote for Webduino IoT devices. There is no build step. Open index.html or index-en.html directly in a browser and use DevTools to inspect runtime behavior and MQTT traffic.

• index.html + js/main.js: Traditional Chinese UI and behavior.
• index-en.html + js/main-en.js: English UI and behavior.
• css/main.css: Shared layout and styling for both entry pages.
• js/common.js: Shared ?type=kebbi / ?type=aicar image-mode switch.
• media/: Shared static assets used by both pages.
• js/mqttClient.min.js, js/paho-mqtt-min.js, js/clipboard.min.js, js/firebase.js: Minified/vendor-style files. Avoid editing them unless the task explicitly requires it. Do not read all of js/firebase.js unless necessary.

• Keep the Chinese and English experiences functionally aligned. If you change shared behavior, update both js/main.js and js/main-en.js unless the difference is intentionally language-specific.
• Preserve language-specific text and storage keys: Chinese uses kebbiMobileData, English uses kebbiMobileEnData.
• Preserve configuration precedence unless the task explicitly changes it: defaults in list, then localStorage, then query params, then Firebase data from the URL hash.
• Preserve MQTT behavior unless asked otherwise: send on topic1, listen on topic2, and keep reconnect-related behavior intact.
• Reuse existing vanilla JS patterns. Do not introduce frameworks, bundlers, or a build pipeline for routine changes.

• Format with npx prettier --write "**/*.{js,html,css,json}".
• Validate changes in a browser by checking:
  • joystick mode and ten-button mode switching
  • settings save/load behavior
  • query-string overrides
  • ?type=kebbi / ?type=aicar rendering
