MAME's card pages, GroovyMAME and yaps2 read 13,000 to 16,700 words of cards. Each entry is now a table row (name, members, status, short hash) that opens to its card in a details block, with the site's filter box and row counter. Pages from 150 entries and every split part use it. Visible words: mame-files-1 16,680 to 1,612, groovymame 14,396 to 1,876. A row costs about five elements, so a part holds 180 cards: MAME goes from 8 parts to 9, the largest at 567 KB and 8,989 elements. Each wanted list (TOSEC, No-Intro, Redump) opens on its counts, then one table folded under a filter box that opens it, in place of a block per DAT. Only the names are searched: indexed descriptions and hashes put the PlayStation page ahead of the PlayStation 2 one. A filtered row stayed visible on a phone: a stacked row's display:block outweighed the hidden attribute on every stacked table.

MAME's card pages read 13,000 to 16,000 words, one card after another,
|
|
before a reader found the archive they came for. Here each entry is one
|
|
row: its name, the facts that tell rows apart, and the full card in a
|
|
closed block under the name. The table is written as HTML so the block can
|
|
hold the card's Markdown. It carries what rehype-stack-tables.mjs gives a
|
|
Markdown table: `data-rb-stack` (one block per row on a phone) and the
|
|
filter box above, which site.ts wires. Without JavaScript the rows show and
|
|
every block opens. A closed block stays in the page, so the browser's find
|
|
and the site search still reach every name it holds.
