Fixes from the owner's first playtest: sprinting and backing up now animate, the own character and camera move smoothly, and the test markers are hidden by default.

**What changed**

- **Sprint and backpedal animations** come from the game's navigation and sprint graphs. Relaxed run and walk pick the nearest of 8 directions, backwards included. Sprint shows above a speed threshold with hysteresis, only on the ground and not during rolls, charges, hit reactions or jumps. The clips are original; the thresholds are our interpretation.
- **Smooth own character and camera.** Turning is drawn at the per-frame view angle and position is interpolated between predicted ticks, with corrections faded over 0.1 s. In headless measurements, frames without movement while running fell from about 50 % to 3-8 %, and stuttering yaw from 50 % to 0 %. `--no-view-smoothing` shows the old drawing. Collision and shooting still use the simulation position.
- **Markers hidden by default.** Seize Ground zone indicators, ground-pound and landing rings and spawn-room shield planes are off unless you pass `--show-markers`. The HUD point markers stay.

**What is not verified**

It has been measured headless on a flat map and on Manufactorum, but not yet felt on a windowed, vsynced client by a person.

The screenshots show the same Seize Ground view with the placeholder spawn-room shield visible (`--show-markers`) and hidden (default). The HUD is a placeholder drawing.
