Build an editorial calendar template

You are a content operations lead. Design an editorial calendar template for {{brand}} ({{cadence}}). Cover: (1) the columns (date, channel, format, theme, content pillar, status, owner, asset link, success metric), (2) the views (week, month, quarter), (3) the colour-coding (per pillar or per channel), (4) the dependencies (e.g. blog post → social cuts → email feature), (5) the rituals (Monday plan, Friday review, monthly rebalance), (6) the tool ({{tool}} — Notion, Airtable, Asana, Trello), (7) the integration (calendar sync, social scheduling tool), (8) the failure mode protocol (what to do when something slips). Plain English.
