The capsule could have rolled on it's side for several meters before coming to a complete stop.

Look again. There is a thing called wind.
P.S. Footage of the landing is very easy to find. Maybe watch it first before posting the observation?

You should have watched the video.
Looking from the side, the "rocket gas" is the shadow of the moving dust. The capsule touched down and tilted on its side due to the high horizontal speed, it moved no more than 2 or 3 meters which is less than the size of the capsule meaning it did not move but only tilted. The dark mark on the ground is from the retro rockets fired at 1 meter above ground, that means the touching down point is further away by some metres depending on the horizontal speed.
Also remember that, the paratrute is cut off immediately after touching down. No wind except perhaps a tornado could move the capsule.

According to Mr. Yang Tianliang (杨天梁), the chairman of the Hainan Commercial Spaceport, launchpad no. 3 and 4 will add at least 32 launches to the spaceport's annual launch capacity. Altogether, the four launchpads will exceed 60 launches per year.
The first image shows the progress on the construction of launchpad no. 4 at the Hainan Commercial Spaceport. Foundation is being laid and flame trench is being excavated. The second image shows the ground being prepared for the construction of launchpad no. 3.

Shenzhou-19 crew carried 37.25kg of experimental samples back from the Chinese space station.

The TV subtitle was wrong in saying "入轨“(orbit insertion), should have been "离轨" (de-orbitting).
It should have been translated as "Further improve safety of controlled de-orbitting of 1st stage" instead of "Improvements will ensure controlled re-entry". The former means that 1st stage de-orbitting is already controlled, they are further improving it. The later may be interpreted as "so far 1st stage de-orbitting is not controlled" because of the word "will".
More appropriately translated to "for launching more station modules". This is a confirmation of modules beyond current ones, i.e. 3 more modules.

This is of some relevance here.
Some illustrations from a paper that I don't have access to. They show a morphing nose cone design that can be used on a hypersonic spaceplane or missile. The nosecone would change shape to improve airframe efficiency and performance (i.e. increase lift, reduce drag, etc.) at different flight regimes.

Don't think there's a flexible material that can take both hypersonic speeds and atomic oxygen without fusing or degrading so I assume this is actively cooled?This is of some relevance here.
