Why TOML for the widget config

Comparing a few config formats for distinguishing always-visible widgets from fullscreen apps, and why I landed on something boring on purpose.

Replace this with your actual writeup. A few things worth covering:

• Formats you considered (TOML, YAML, JSON, a custom DSL) and why you ruled them out
• How the schema distinguishes widgets vs. fullscreen apps
• Per-app browser and zoom settings — how those are expressed
• Anything about validation or defaults
