android: the whole discography, on a page of its own

The artist page already filed every release the desktop's way, but it only
ever showed one category at a time and it showed all of it: no slice anywhere
in that grid, so an artist with 140 releases drew 140 cards. There is a page
now — All in front of the categories, a sort, a grouping by year, and the
editions opened in place under their own record, which is the part a flat
list loses — and the grid behind it stops at twelve with the way down under
it. It is the same classifier twice over the same cached albums, which the
desktop cannot do because its filing waits on a background description
harvest; the three things its own page has and this one does not — a
tracklist per record, an accent sampled per cover, the scroll-led banner —
are 140 calls and 140 decodes over mobile data for rows that are one tap
away, and ANDROID.md says so rather than leaving them looking forgotten.

The list caps at sixty with the rest a button away, before the grouping, so
the last year on screen can be a part of itself; under a name order By year
is not offered, because the years would repeat out of sequence. The mock
gains a 140-record artist so both caps are walked rather than argued about.

+Discography head with **All**, and from under its grid with "Show all N
+Albums" — which is also where that grid now stops: it shows twelve of the

+cards. The page is the desktop's `CatalogDiscography.svelte` reduced to the
+four things it has that the artist page's tabs do not: **All** in front of
+the categories (built by CONCATENATING the per-category families, never by
+re-folding the whole set — a single sharing an album's base title would fold
+into it as a phantom edition), a **sort** (newest, oldest, A–Z, Z–A), a
+**grouping** by year, and the **editions kept whole**, opened in place under
+their own record. Three of the desktop's are deliberately left behind: the
+per-record tracklists (140 records is 140 `catalog_album` calls over mobile
+data, for rows one tap away on the record page), the per-record accent
+sampled from each cover, and the scroll-led banner. The year is written into
+the list where the desktop has a sticky year rail — a phone list is read top
+to bottom. The order and the grouping live on the nav entry and are edited
+from the **Sort & group** sheet, Library's own idiom; under a name order By
+year is not offered, because the years would repeat out of sequence, and the
+sheet says so. The list is capped at sixty rows with a "+ N more releases"
+button (Browse's rule), and the cap is taken BEFORE the grouping, so the last

+second time over the same cached albums. The desktop cannot do that: its
+filing depends on a background description harvest and deferred MB type
+hints a second page would not read, which is why `CatalogDiscography.svelte`
+takes the artist page's computed tab list as the same array object instead.
