The map credits OpenStreetMap on the map, and shrinks the credit once it is used
Only the About page and the README said where the streets came from, which is not
where anyone looking at a map would look for it. OSMF's Attribution Guideline asks
for the credit in a corner of the map itself, visible without having to interact
with it, and lets an interactive map collapse it once the reader pans or zooms so
long as the licence stays findable — an "About option in a menu" is its own worked
example, and we have one.
So the full-screen map is arrived at with "© OpenMapTiles · Data from
OpenStreetMap" — OpenFreeMap's required line, less the half it calls optional — in
its bottom-right corner, and the first key it handles collapses that to "©
OpenStreetMap", which OSMF names as an acceptable form outright. The OSM credit
therefore never actually goes away; the collapse only spends OpenMapTiles' half of
the line. It costs the app no chrome at all: it is stamped over the right end of
the drawing's own bottom row at paint time, so no title atom, no footer character,
no body line, and no reveal key to buy a chip on a full F-key lane. Where the
PicoCalc echoes a find query over that same row the two share it, query left and
credit right, and the query is the half that gives way.
The node page's location preview takes the short form throughout: it is a picture
on somebody else's page rather than a map they went to look at, it has no pan or
zoom for a collapse to trigger on, and the short form is complete standing still.
The About page and the README now name OpenMapTiles too, which neither did, and
the page says out loud that the URL it prints is where the map's corner points —
nothing on a framebuffer console is clickable.
