run_environment.csv is keyed by (build, device) but the env lookup was keyed by
build alone — the Redmi rows overwrote the A36's and the gate scorecard lost its
2.38.2 baseline on every surface. Same hole in the per-surface charts: a surface
naming no device charted all devices (21 Redmi points on 8 A36 charts). Both now
scope to one phone; unnamed = the gate phone.
Adds a low-end scorecard, an A36-vs-Redmi comparison and per-surface Redmi trends
under docs/android/lowend/, published apart from the gate — the gate stays one
reference phone by design.
Gate verdicts are also withheld when only one side is below the measurement floor
(2.38.2 read Buy and Home at ~0.1s, so a normal 0.6s printed as "+0.5s slower").
