dsh-peak-indicator: DeepSeek Peak/Off-Peak Pricing Status Indicator

`dsh-peak-indicator` is a DeepSeek Harness plugin maintained by adesbusy that provides a visual display of the current pricing status. It indicates billing periods using sidebar dots (amber for peak hours, green for off-peak hours), allowing users to confirm the rate at a glance without leaving the interface. The plugin calculates time based on UTC, strictly follows the official rules, and supports mouse hover to view detailed rates, countdowns, and weekly rules. Its built-in holiday logic falls back to weekday rules when holiday data for 2027 is missing, ensuring consistency. Run `dsh plugin add github:adesbusy/dsh-peak-indicator` to install, then refresh the page to activate it.
