The Driver asked for map detail: "a typical map poster needs details on the map that is not hard to see, but not so much that it becomes too complicated — cities and capitals makes sense." Natural Earth 1:10m, PUBLIC DOMAIN: no attribution to carry onto a printed packet, vendored so a build is reproducible offline with no runtime dependency. Trimmed at vendor time from 4.9 MB / 7,342 places to 170 KB / 2,573 (national + admin-1 capitals, plus cities >= 250k) because a poster cannot legibly carry 7,342 dots and the packet is downloaded. The layer is deliberately SUBORDINATE. It answers "where am I?"; the people-group pins answer "who do I pray for?", and they keep the only saturated colour on the sheet. Capitals are ringed dots (the cartographic convention), cities plain dots — shape and value carry the rank so no extra hue is spent. Reading order stays country > province > city > people group. Three things had to be right, each found by measuring rather than by looking: 1. RANK BY RELEVANCE TO THE SUBJECT, not by global importance. Sorting by capital-rank then population is the obvious choice and is wrong: the neighbours are usually bigger. On the Laos sheet that sort spent the budget on 12 Vietnamese and 8 Thai cities and printed exactly ONE Laotian place while 12 more sat available — a poster of Laos labelled with other countries' cities. Subject countries now win the budget. 2. DERIVE THE SUBJECT FROM THE PINS, not from the zone. zone.adm0 exists only on generated city/country zones; the hand-authored lists carry a selector in SEVEN shapes (pg_slugs, country_code, country_codes, wagf_block, wagf_region, union, deaf_predicate) and the most common names no country at all. Reading zone.adm0 produced an empty set and the whole sort silently did nothing. The pins always know their own country. 3. AVOID THE PINS USING WHERE THEY ARE DRAWN. Two distinct errors here. Testing the label's ANCHOR is wrong for a right-aligned label, whose glyphs run leftward from it — so the box is tested, not the point. And the de-overlap relaxation MOVES badges after projection, so proj(pin.lng,pin.lat) is not where the badge lands; this block therefore runs AFTER layoutLabels and reads laid[].px/py. With the naive tests, 7 of 25 labels sat within 14px of a pin and Saravan landed 1.4px away while the check reported it clear. Now: 291 labels across 16 posters, ZERO overlaps. A city that cannot fit clear of a pin is dropped — a missing city costs nothing, an obscured people group costs the poster its purpose. ⚠ ROADS WERE REQUESTED AND DELIBERATELY NOT SHIPPED. Natural Earth's 10m roads layer was fetched and measured: ZERO features for LAO, MMR, KHM, VNM, THA, NPL, BTN, TCD, NER, MLI, SOM, AFG, YEM, IDN, IND and CHN. Its coverage is essentially USA/CAN/MEX. It would draw a dense network on a US map and nothing on every country these packets are for — a broken-looking map exactly where it matters. Real road coverage needs an OSM extract: a much larger dependency with an ODbL attribution obligation, so it is carded rather than half-shipped. See data/README.md. Note: zone oceania-indonesia fails generation with a header-overflow error. Verified pre-existing on a clean tree — unrelated to this change. |
