Blue Tier 2: Tiered access to screens by grade band playbook

This priority sets a grade-band framework for school-issued devices including hands-on, print-based instruction in the earliest grades, shared cart-based devices in middle school, and one-to-one devices only in high school with real caregiver opt-in and safeguards. It pairs naturally with Healthy Defaults and the Social Media Use Policy, but it doesn’t require either one: a district can adopt this on its own.
