- Removed the intermediate step of storing all variants in an environment variable to prevent exceeding size limits. - Updated the logic for selecting variants based on changes in the GitHub Actions workflow. - Enhanced the LCD panel configuration for `esp_lcd_ili9486` and `esp_lcd_nv3030b` to support new RGB element order handling. - Adjusted SSD1306 display initialization to ensure compatibility with different IDF versions by using individual field assignments.
