How this map was built

Cathay publishes 40 Business / 32 Premium Economy / 296 Economy = 368 for 77K. Every row, seat letter, partial row, cabin break and monument is reproduced from Cathay's official CX_777_300ER_77K_2026.png, so layoutProvenance is published_map and no cabin is marked derived. Business rows are 11, 12, 15-19 and 20-23; row 19 has only A/K and row 20 only D/G. Premium Economy is rows 30-33. Economy is rows 39-57 and 59-72 with the published rear taper. The live accessible description identifies 19A/K, 43A/K and 59A/K as non-viewing seats. Cathay's extra-legroom icons identify 40C/H plus the six side seats at rows 43 and 59; these 14 fee-tier seats remain inside Economy but resolve to N in cabinSummary, leaving 282 ordinary Y seats. The annual report says the Aria retrofit continues, while both 77K and 77J remain on Cathay's live selector; therefore 77K is linked as the retrofit source to 77J. Unpublished numeric dimensions are omitted. Window alignment is unknown except for Cathay's explicitly non-viewing seats.
