+Operator asked to replace the scale-ring `⊖ out / in ⊕` buttons with a **circular
+"Altitude" knob** that turns all the way around (including abyss→cosmos). Built a
+turnable SVG dial in `simulator/static/app.js` (`buildDial` / `renderDial` / drag +
+wheel handlers) + `style.css`: cosmos (highest) at top, clockwise descends
+cosmos→orbit→coast→reef→abyss and **wraps** back up. Dragging accumulates rotation
+and commits whole detents on release (a big spin → one fast blended pass, reusing
+the proven wheel/detent path); scroll the knob to step; tap a label to jump the
+shortest way around. **Pure frontend** — the endless ring + wrap already existed
+server-side, so no engine/API change. JS syntax-checked; 23 sim-API tests green;
+live probe confirmed the dial replaced the buttons and the abyss→cosmos wrap is
+intact. Merged as **PR #18** (`main` at `7a32ff1`). Visual look still operator-by-eye
+(no Chrome on this box).
