feat(upg-100): the prayer card deck prints as CARDS, not as paper
Driver: "the print dialog that opens up needs to show all the cards not in a
paper format but a CARD format, the aspect ratio that is used in the card
generator."

The deck set @page{size:letter portrait} and gave each card height:100%, so 95
cards printed as 95 mostly-empty 8.5x11 sheets — and with NO photo, because
image_url was never in the fetch. Measured: 95 of 95 groups DO have a portrait,
so the omission cost every card the one thing that makes it a prayer card.

Now the PAGE IS THE CARD. @page takes the stock's own inches, so one card is
exactly one page: 95 cards -> 95 pages at 180x252pt (2.5x3.5in). Print on
cardstock and cut, or send the PDF to a card printer. The stock is a user
choice, per the Driver's ask to "choose the layout of the print dialog to choose
the aspect ratio": poker 2.5x3.5in (default), postcard 4x6in, A6.

⚠ @page SIZE MUST BE EXPLICIT INCHES. Chromium SILENTLY falls back to letter for
a named size it does not know: `size: A6 portrait` yields 612x792pt with no
error of any kind, while `size: 2.5in 3.5in` yields exactly 180x252pt. The gate
therefore asserts the MEASURED MediaBox — a check that grepped the stylesheet
would pass a deck that prints as paper.

Card content follows doxa-life/promotional-material-generation, the Python data
pipeline feeding the InDesign template: per language it emits Description,
Religion, Area, Country, a QR to that group's page, and the URL. Ported to
JavaScript here so the deck generates in the map app on click. Description and
Area are NOT available from this API — measured 0 of 2107 records carry either —
so the card is built from what genuinely exists: portrait, name, country,
population, language, religion. An empty block reserved for data that never
arrives is worse than a card designed around the data there is.

QR is hand-rolled (library/packet/qr.js, ~200 lines): byte mode, level M,
smallest fitting version, mask 0. A symbol is pure computation, so it costs one
small file instead of a package and runs identically under Node and in a tab —
the standing constraint is "without adding a lot of dependencies on the
internet". A QR that does not scan looks exactly like one that does, so it is
verified by DECODING: an independent reverse-path decoder re-derives the data
placement, unmasks, de-interleaves and parses the header. 5/5 round-trip,
including version selection (v2 for a short URL, v3 for real ones).

I18N: the QR encodes the LOCALISED profile URL, so a Spanish card scans through
to the Spanish page — verified, pray.doxa.life/es/aheu. Strings fall back per
key; checked with a partial Spanish block ("Ora por ellos" rendering while
Language/Religion stayed English).

★ ONE BUG THE NUMERIC GATE PASSED, worth recording. The first deck rendered
"LAO", "thm", "EAN" — raw codes on a card a person is meant to pray from —
because normalizeRecords() flattens each { value, label } dict to its VALUE and
parks the label under <field>_label. A gate counting "4 rows rendered" passed
it: the rows were there, just unreadable. The gate now asserts the values are
HUMAN-READABLE, not merely present.

Verified by check:card-deck across all three stocks: 95 cards / 95 pages, 0
broken portraits, 95 QR codes with real symbols, 0 raw codes, 0 overflow.
