* feat(catalog): group the sidebar by what you came to make
Nineteen shelves in one column is a list to read, not a menu to scan, and two
of them were oversized: Effects held 54 items and Showcases 38, two thirds of
which were near-identical code-snippet themes.
The shelves now sit under eight openable sections named for what a reader is
making, and the editor and terminal themes get a shelf of their own. Every
existing shelf name survives underneath, so a bookmark into the catalog still
lands where it did.
Two things had to change to support nesting. The summary count walks sections
as well as shelves, and the filter that preserves hand-written groups now
recurses: a section holds groups rather than pages, so a check that only read
`pages` found nothing generated in one, kept it as if a human had written it,
and appended a fresh copy on every run.
* fix(catalog): type the nested page count
* fix(catalog): nest shelves inside pages so the sidebar renders them
