Eight of the twelve named styles resolved their MapLibre URL to
basemaps.cartocdn.com. Those are keyless today -- verified live, style JSON
and a real vector tile and a font all 200 with no token -- but CARTO's own
docs reserve the right to extend the key requirement to vector tiles. That
is a future silent outage already shipped, and the same single-point-of-
failure shape we are trying to escape by leaving the URL-restricted Mapbox
token. A dependency that is free today and gated tomorrow is a deferred one.
dark-matter -> openfreemap dark (midnight-glow, dusk, ink, wayfinder-night)
positron -> openfreemap positron (paper)
voyager -> openfreemap liberty (satellite, hybrid, wayfinder-day)
Each replacement verified before the swap: 200 keyless, zero keyed URLs in
sources/glyphs/sprite, real tiles serve. Built output now has zero CARTO
references. Embed suite 40/40 pages mount cleanly.
The header records the bar for adding a style here: keyless, commercial use
permitted, self-hostable. MapTiler and Stadia free tiers fail the second.
The page URL's ?utm_source= now outranks config/global/default in every outbound
people-group link — an iframe embedded as <page>?utm_source=agwm, a partner page
carrying its own ?utm_source, or a host page like /embed/map/?utm_source=agwm
all attribute their traffic automatically. Applied in the shared popup and both
dashboard drawer links.
