@@ -95,6 +95,12 @@ Pure scrub logic kept separable + unit-tested; Playwright E2E extended to assert
   hence "only sometimes." **Fix:** `cancelFade(el)` supersedes any in-flight fade when a new fade starts
   (`fadeVolume`) or a direct volume is set (`ensurePlaying`). Added `window.__hefFade` seam + a deterministic E2E
   that PROVES it (fails with the fix disabled, passes with it). Playwright **10 green**.
+### Eyeball round 4 — transition speed (1 commit)

+- **Request:** slow click/auto transitions ~2x and make them the SAME speed between any two altitudes (2 away =
+  2× as long as 1). `autoScrub` was a fixed 600ms total regardless of distance. Now duration is PROPORTIONAL:
+  `PER_ALTITUDE_MS=1200` (≈2× the old 600) × |distance|, so a label-click/wheel jump of N altitudes takes
+  N×1200ms — constant per-step speed. Manual drag unaffected. E2E asserts a 2-step jump ≈ 2× a 1-step. 11 green.
 - **Resume:** merge + `wgl-session-finalize` on operator go, OR next eyeball round of tweaks.
