Each pin renders at actual map size. Set a category's Box and Type hex and the preview updates live + saves to Supabase. One colour definition per category drives the map pin, the place-card chip box and the chip type together. Leave Type on Auto to follow the brand rule — cream on dark fills, navy on light — or set it explicitly. The contrast ratio next to each chip is the real WCAG number at the chip's 10.5px type; below 4.5:1 the label is hard to read on a photo. /guide-map.html and /reader-map.html read from the same table — so your changes here render on the live maps.
