Adds a Playwright spec that runs only on the chromium-mobile project
(Pixel 5, 393 × 851) and gates the two regressions the previous
chart commit cleared:
- Every chart card on the dashboard keeps its range tabs on a single
horizontal row (asserts that all `[data-slot=chart-range-tab]`
inside a card share one rounded `top` coordinate). Mock data feeds
every chart 30 days of measurements + 30 days of compliance points
so the controls row actually paints with all chips and tabs.
- Every recharts x-axis paints at most seven visible tick labels at
Pixel 5. The helper caps at six; the seven-tick allowance covers
Recharts' preserveStartEnd interaction with rounding.
The PROD probe script that drove the audit is also committed at
.planning/v1419-a2-prod-probe.mjs for future regression runs, with
the findings recorded in .planning/phase-A2-mobile-findings.md.
