lhci treats every LHCI_* environment variable as a command-line option, so LHCI_PRESET=mobile reached `lhci assert` as an invalid --preset and failed both jobs after the audits had run. Use LIGHTHOUSE_FORM_FACTOR instead. Also upload the reports: upload-artifact v4+ skips dot-directories such as .lighthouseci unless include-hidden-files is set.

// Lighthouse CI: `npm run test:lighthouse` builds the Node adapter output, serves it and audits the

// public pages. Any category below 90 fails the run (and so the PR).
|
|
// Set LIGHTHOUSE_FORM_FACTOR=desktop to audit with the desktop profile; the default is Lighthouse's
|
|
// mobile profile (slow 4G + CPU throttling), which is the stricter of the two. The variable must not
|
|
// start with LHCI_: lhci treats those as CLI flags, so LHCI_PRESET was passed to `lhci assert` as
|
|
// an invalid `--preset`.
