Clearer methods, practical additions
- Rewrote About and the editorial policy to identify the publisher, disclose optional digital-product sales and remove unsupported descriptions of testing and review workflows.
- Added a free brew notebook for quantities, personal taste notes and CSV export. Its concentration and powder-cost formulas are visible, and saved records stay in the user's browser.
- Added guides for pack usage, small-party preparation, foam troubleshooting, sweetened blends and water-only matcha versus lattes. Worked quantities are labelled as calculations rather than kitchen-test results.
- Expanded the troubleshooting reference with routes for clumps, dilution and preparing ahead.
- Revised dose guidance to distinguish producer examples and arithmetic from universal serving recommendations. Revised sweetener and digestion articles to make their evidence limits more explicit.
- Removed automatic timed sales overlays. Optional product cards remain clearly labelled, with prices and links to previews. Advertising ownership verification remains separate from ad serving.
