Using these docs

• Every page as MarkdownUse the Markdown actions under a page title, or add .md to the page URL. Useful for feeding a page to an AI assistant.
• No figures in the textPrices, allowances and caps change, and a copied number goes stale silently. Each page links to the screen that shows the live value.
• Search everythingSearch at the top of every page covers every guide. The sidebar lists them by topic, in the order you meet them.
