dc 66d5fecb0e feed: embed the special missings recording, and correct the copy
Embeds the "Special Missings in Data Controller" recording from vid.4gl.io as a
responsive PeerTube iframe, in place of the older YouTube embed, and drops the
stray `video: [...]` line that was sitting in the body as literal text.

Copy corrections, each verified against the running app rather than the source:

- the range rules compare in SAS's order, so MINVAL .A with MAXVAL .C takes .B
  and refuses .D, a missing fails a numeric MINVAL and passes a numeric MAXVAL,
  and a number sits above every missing. The old wording said the range rules
  step aside for a missing value
- a lone "." is another way of typing the regular missing; the previous claim
  that a literal "." is refused in favour of null is not what happens
- a strict dropdown does accept a special missing when its list holds one (the
  list shows it as a bare letter), and still rejects a value that is not listed
- NOTNULL rejects a special missing, and a primary key column is NOT NULL
  whether or not a rule is configured for it

The LinkedIn version of the post is kept in sync, and carries the new video URL.
