poster-render gains three side-lane formats (60x96, 66x66, 36x60), and
check:poster-design-catalogue requires SHEET_FORMATS to list exactly what
FORMATS defines, so it failed on those three. They are now listed, near
the top after the 3 x 3 sheet, with India as their sample: India is the
one country countrySheet.js prints on a large sheet (LARGE_SHEETS).
map-sheet.country.60x96 draws through makeCountrySheet, the one country
sheet path, so its card shows the real whole-India poster. 66x66 and
36x60 are listed but not drawn: no country prints at those sizes yet, and
the shared path would hand back India's 5 x 8 ft sheet under their label.
Their details say so (posterDesign.missing.largeFormat, 11 locales).
The check fails on the three formats without this commit and passes with
it.
