256GB storage allocation

Three-layer sync

Local first. Mesh second. Cloud only when convenient.

Each node serves clients from its own 256GB cache. Peers rsync deltas to each other during the 02:00–05:00 window. The cloud origin only pushes monthly content releases — there is no per-view backhaul cost.
