/**
 * sme-demo.spec.ts — End-to-end Playwright happy path for the FIRST
 * SME tenant on a healthy otech (issue #805 / parent epic #795).
 *
 * This spec is the load-bearing investor-demo proof. It walks the full
 * 6-step happy path from marketplace signup through alice's daily
 * workflow + billing read-out, and emits 1440×900 screenshots at every
 * assertion so the DoD checklist on #805 is satisfied with visual
 * evidence rather than narrative.
 *
 * ── Mock-mode vs live-mode ────────────────────────────────────────
 *
 * Today the spec runs against the local Vite dev server with every
 * back-end surface mocked via `page.route`. This is the only way to
 * keep CI green while the tenant-provisioning pipeline (#804) and the
 * billing UI surfaces are still in flight. The mocks live in
 * `e2e/lib/sme-fixtures.ts` — each one is wire-shape-faithful to the
 * canonical handler (sme_users.go, tenant_discover.go) so when #804
 * lands, the spec opts out by simply not calling the relevant
 * `installXxxMocks()` helper.
 *
 * Steps that depend on UI surfaces NOT YET LANDED at SHA-of-record are
 * marked with `test.fixme` + a TODO comment linking to the blocker
 * issue (#804 for tenant-provisioning, #802 sub-task for billing UI).
 *
 * ── Why one spec instead of six ───────────────────────────────────
 *
 * The DoD is "first SME, full happy path, behaviour-verified" — the
 * narrative IS the evidence. Splitting into separate spec files would
 * make it possible for one step to silently regress while the others
 * stay green. Per docs/INVIOLABLE-PRINCIPLES.md #2 (never compromise
 * on quality), the spec is intentionally a single linear walk so a
 * regression at step 3 fails the suite, not a cosmetic detail.
 *
 * Tagged `@sme-demo` so the CI workflow can grep it independently.
