Sit-and-water reminder for DeepSeek Harness, with a cat that sits in the corner of the Web GUI. A focus cycle of 30-90 minutes ends in a centered overlay plus a triple chime that gets you up to walk and drink; the later button answers with one real sourced case about prolonged sitting and one about dehydration (built-in library of 17 entries, each with publisher, date and a link to the original); stopping produces a session report with worked time, completed rounds, successful interruptions, snoozes, suggested drinks and a good/mid/bad grade. The cat can be dragged anywhere with its position remembered and loops one animation per state. The timer and the ledger live in the host half, so a page refresh never loses a cycle; it only reminds while a DSH page is open. Cycle lengths, chime volume, cat opacity and grade thresholds are configurable on the plugin settings page.
