Measured on the 60x96 print: every photo beside a name rasterised as the browser's broken-image glyph. An SVG
rasterised through <img> is an isolated document that fetches no external resource, and none of the people-group
photo hosts (media.joshuaproject.net, joshuaproject.net, images.peoplegroups.org and its resizer,
peoplegroupspublic.blob.core.windows.net, s3.doxa.life) sends CORS, so a photo cannot be inlined as data: in the
browser either.
- poster-raster.js: rasterPoster drops every <image> whose href is not data: (the basemap tiles are data: and stay),
so a download shows the paper, never the glyph. hasExternalImages() says when a sheet carries such photos.
- PosterWall: printing a generated sheet that carries photos prints THE SHEET ITSELF through printDocument, where
the photos load, on its own @page (60in 96in), instead of a raster shrunk onto letter. Same HUD steps.
- check:side-lanes: photo arms (0 external images reach the raster; the wall prints such a sheet as a document),
each with a poison in its self-test.
- check:side-lane-photo-pixels: the pixel side, a browser gate (a data: photo draws red; 99/99 external slots stay
flat; without the strip 0/99 do). Declared on-demand until its first browser-seat run.
