The content of PageStylesheet is:
<$list filter="[is[shadow]tag[$:/tags/stylesheet]]
[!is[shadow]tag[$:/tags/stylesheet]]">
<$transclude/>
</$list>
This selects all tiddlers tagged with "$:/tags/stylesheet", and then
transcludes their *content* into the PageStylesheet.
To get a list of the *titles* that match this filter, you could create a
new tiddler, containing:
<$list filter="[is[shadow]tag[$:/tags/stylesheet]]
[!is[shadow]tag[$:/tags/stylesheet]]">
{{!!title}}
</$list>
However, while this will display the titles, they will not be "wikified",
so they will not be live tiddler links.
Alternatively, omit the <$list>...</$list> widget entirely, but use the
same filter surrounded by tripled curly-braces, like this:
{{{[is[shadow]tag[$:/tags/stylesheet]] [!is[shadow]tag[$:/tags/stylesheet
]]}}}
This will render the filter result (the list of tiddler titles), with full
"wikfication", creating live tiddler links that you can then click to
navigate to the actual CSS-bearing shadow stylesheet tiddlers. Q.E.D.
Note: to add customizations, you should not edit those shadow stylesheets
directly. Rather, you should copy/paste the relevant CSS rules from those
stylsheets in a new tiddler, tagged with "$:/tags/stylesheet", and then
edit the rules there. Because non-shadow stylesheets are trancluded
*after* the default shadow stylesheets, any modified rules contained in
your custom stylesheet tiddler will be applied last, superceding the
corresponding default CSS from the shadow stylesheets.
