Verifies the mobile layout from #5 with a real browser engine instead of by hand on a phone. make frontend-viewport-test builds dist/, serves it from the same digest-pinned nginx image and the same nginx.conf the shipping container uses, and drives a digest-pinned headless Chrome against it over CDP. Viewport widths are derived from the app's own CSS rather than from a list of phone models: the @media conditions in src/styles.css and any Tailwind responsive prefixes in the markup are parsed, and each breakpoint is tested one pixel below, exactly on, and one pixel above. max-width: 768px matches at 768, and a generic 375px test sails past that boundary entirely. Four anchor viewports are added with stated reasons: a 320px floor, a desktop baseline, and two phone-landscape sizes straddling the breakpoint. Assertions are on computed layout, not screenshots: horizontal overflow, elements past the viewport edge, clipped text (deliberate ellipsis truncation excluded), 44x44 minimum tap targets, and genuine reflow of the host rows checked on both flex-direction and geometry. Probing and gateway detection are asserted to still run at narrow widths, since the early-return mobile path rejected in #8 is what would silently regress. Screenshots are written to tmp/viewport/ as artifacts alongside the results, not as the evidence. puppeteer-core rather than playwright: it is the one variant of either that never downloads or bundles a browser, so the browser stays a digest-pinned image and the npm side is pinned by yarn.lock integrity. The browser container runs on an --internal docker network with no route off the host; the harness answers the app's latency probes itself from a fixed delay table so the rows render a realistic spread of value widths. Kept out of make check: it needs Docker and takes minutes, where make test has to stay under 20 seconds. The harness was observed failing before being trusted, twice: a planted 900px fixed-width element in a host row, and the mobile reflow rule neutered. Both reverted. Against the current layout it reports two real defects, filed as #42 (horizontal overflow at 320px) and #43 (tap targets below 44x44).
