Why it matters
Research cited by the legacy site notes that one interruption can take more than 23 minutes to fully recover from. Nereus is built to stop the interruption before it starts.
Focus with purpose
Protect attention, then turn focused hours into visible momentum.
The original site connected deep work to ocean cleanup: for every 100 community focus hours, one pound of plastic is removed from the ocean.
I kept that idea here as supporting proof of mission, while keeping the main conversion path centered on installing Nereus and starting a protected session.
