Resolve one stable battery source independently of the functional device face,
include battery-only ticks in immutable render snapshots, and add a default-on
shared preference. Keep LED strips excluded and Zigbee captions above the
passive, out-of-flow indicator. Use the owner's accepted four MDI icons in the
designer's frame geometry and colours.
Include resolver/backend/browser/pixel contracts and three new golden scenes.
Recalibrate the owner-approved absolute/raw size budgets; preserve the existing
initial View rolling ceiling and band. Lazy extraction remains separate #805.
