+/**
+ * T03 — Compression Studio (Tela A) smoke e2e (gaps v3.8.42).
+ *
+ * The studio's reducers/renderers (compressionFlowModel, WaterfallInspector,
+ * CompressionCockpit, PlayView/CompareView) are unit/vitest-covered. What unit tests
+ * CANNOT catch is a client-side render / hydration crash on the real page — the same
+ * "no `useTranslations` trap" risk the compression-UI plan flagged. The existing
+ * combo-live-studio spec guards `/dashboard/combos/live`; this is its missing
+ * counterpart for the dedicated compression studio (Tela A), which that spec does not
+ * touch.
+ *
+ * It loads /dashboard/compression/studio and asserts the studio mounts (Play tab + its
+ * lane), then flips to the Compare tab and asserts the switch took effect. The
+ * visibility assertions ARE the hydration-trap guard: a render-time crash would mean
+ * none of these testids ever appear.
+ *
+ * Out of scope (kept unit-covered, to stay non-flaky): driving a live WS compression
+ * cascade (needs `compression.step` events an e2e cannot inject) and asserting console
+ * output (dev-mode on-demand compilation emits transient fast-refresh noise).
