Stage case for representation, a page script, and a table.
Self-review case. The page and query results below are predictions.
A file URL is not HTTP. The SQL file is not part of the HTML file.

Representation:
The displayed word desk-lead uses nine ASCII characters.
UTF-8 stores those nine characters as nine bytes.
Counting characters and counting bytes agree for this ASCII word.
They do not agree for every word, as the Unicode lesson showed.

Page script:
Before the click, #role text is reader.
The click handler sets textContent to desk-lead.
Predicted DOM text after the click: desk-lead.
The script does not open the SQL file and does not send a request.

Table:
name | lane
ria  | a
sol  | b
tez  | a
Query: SELECT name FROM shifts WHERE lane = 'a';
Kept rows: ria and tez. sol is left out.
SELECT does not change the stored rows.

Boundary:
Changing the paragraph does not change the shifts table.
Changing a row would not change the paragraph unless some other,
absent program copied it. This case has no such program.
No server permission is granted by the new label.

Rubric: name the byte count for desk-lead, the DOM text after the click,
the kept names, and the store the click does not modify.
