Checkpoint-1 bug: the row partial's docstring used a multi-line {# ... #}
block. Django's single-line comment syntax doesn't match across newlines,
so the opening {# and closing #} were treated as literal text and spilled
into every rendered row — flooding the table body with the raw comment.
Worse, the browser partially parsed the literal <tr> inside the comment
text as an HTML tag, breaking the table layout entirely.
Fix: moved the multi-line docstring into a {% comment %}...{% endcomment %}
block and compressed three other multi-line {# #} blocks to single lines.
Also tripped on a second foot-gun: you can't put literal {# or #} inside
a {% comment %} block — Django's tokenizer still sees them as a nested
comment marker. Removed the meta-note about "{# ... #} is single-line
only" from inside the comment block.
All 58 tests pass. Table renders correctly with all 10 columns + type
badges + row actions visible.
