Authenticate with your Google account\n2. The app will create a secondary calendar for metadata if it doesn't exist\n3. View your calendar in the vertical-scrolling year view\n4. Create formatting rules for events\n\n## Formatting Rules\n\nEvents can be formatted based on various criteria:\n- Event title contains specific text\n- Event is in a specific calendar\n- Event has specific properties (all-day, recurring, etc.)\n- Custom rules using simple expressions\n\nFormatting options include:\n- Background color\n- Text color\n- Custom display format (e.g., \"XYZ✈ABC\" for flights)\n- Visibility options\n\n## Future Extensions\n\nThe architecture is designed to easily add new views and interfaces in the future.","label",[135],"f169bf18-3668-11f0-8c1e-9e149126039e",["D",1747848480317],[44],"bd5c8598-3668-11f0-88eb-9e149126039e","backend","67720bca-35c7-4bf0-9d93-812d648b7dd1",2,["D",1747848392985],[149],"pulls","branches","forks","envVars",{"_161":163,"_164":141},"connections",{"_161":141,"_162":141},"count","unfilledCount",3,"emptyCount",{"_48":148,"_32":149,"_30":150,"_137":-5,"_41":42,"_40":151,"_139":63,"_38":234,"_13":141,"_34":46,"_36":-5,"_24":25,"_143":-5,"_177":235,"_27":236},{"_48":230,"_32":229,"_30":224,"_137":150,"_41":42,"_40":163,"_139":63,"_38":231,"_13":141,"_34":46,"_36":-5,"_24":25,"_143":-5,"_177":232,"_27":233},{"_48":221,"_32":222,"_30":223,"_137":224,"_41":42,"_40":163,"_139":63,"_38":225,"_13":141,"_34":35,"_36":226,"_24":25,"_143":-5,"_177":227,"_27":228},{"_48":217,"_32":216,"_30":211,"_137":150,"_41":42,"_40":67,"_139":63,"_38":218,"_13":141,"_34":46,"_36":-5,"_24":25,"_143":-5,"_177":219,"_27":220},{"_48":208,"_32":209,"_30":210,"_137":211,"_41":42,"_40":67,"_139":25,"_38":212,"_13":141,"_34":35,"_36":213,"_24":25,"_143":-5,"_177":214,"_27":215},{"_48":204,"_32":203,"_30":197,"_137":150,"_41":42,"_40":198,"_139":63,"_38":205,"_13":141,"_34":46,"_36":-5,"_24":25,"_143":-5,"_177":206,"_27":207},{"_48":194,"_32":195,"_30":196,"_137":197,"_41":42,"_40":198,"_139":63,"_38":199,"_13":141,"_34":35,"_36":200,"_24":25,"_143":-5,"_177":201,"_27":202},{"_48":187,"_32":188,"_30":61,"_137":150,"_41":42,"_40":151,"_139":25,"_38":189,"_13":141,"_34":35,"_36":190,"_24":25,"_143":191,"_177":192,"_27":193},{"_48":145,"_32":44,"_30":45,"_137":-5,"_41":42,"_40":14,"_139":63,"_38":184,"_13":141,"_34":46,"_36":-5,"_24":25,"_143":-5,"_177":185,"_27":186},{"_48":180,"_32":33,"_30":31,"_137":45,"_41":42,"_40":14,"_139":63,"_38":181,"_13":141,"_34":35,"_36":37,"_24":25,"_143":-5,"_177":182,"_27":183},{"_48":134,"_32":135,"_30":136,"_137":-5,"_41":42,"_40":138,"_139":25,"_38":176,"_13":141,"_34":21,"_36":142,"_24":25,"_143":-5,"_177":178,"_27":179},["D",1747848372367],"children",[],[135],"f169b2e8-3668-11f0-8c1e-9e149126039e",["D",1747848480317],[],[44,33],["D",1747848480317],[174],[44],"bd5c7a44-3668-11f0-88eb-9e149126039e","index.ts",["D",1747848392985],"import
