library/maps/rtl-text.js installed the RTL text plugin for MAPBOX only
(window.mapboxgl, from api.mapbox.com). So every MapLibre map, i.e. every
keyless embed, drew RTL place names as disconnected, reversed glyphs.
Measured on the Prayer Walk Planner's printed Arabic sheet.
Under it was a second gap. Bundle entries call the installer at LOAD
time, before useMapInstance has lazily injected a MapLibre engine, so even
an engine-aware installer found nothing to install into.
- rtl-text.js is engine-aware. Mapbox is unchanged (same URL, same lazy
call). MapLibre gets the same plugin package from jsDelivr, keyless and
not api.mapbox.com, so keyless pages still make zero Mapbox requests.
New ensureRtlTextPlugin(gl) waits until it is LOADED, for callers that
capture a single frame (print).
- useMapInstance installs it the moment an engine global exists, the one
point every map passes through.
- The planner drops its private copy for the shared helper.
Measured: a print map of downtown Cairo (MapLibre, keyless) shows shaped
Arabic street and place names (شارع التحرير, مسجد الطباخ …); plugin
status "loaded", fetched from jsDelivr. check:gallery-embed passes js,
iframe, neighbour and linked (14 tabs); :maplibre passes;
check:prayer-walk-planner passes.
The shared change reaches all 11 bundles that compile initializeMap, and
all are rebuilt here. check:shared-reached gains an rtl-text-maplibre
marker (10/10 consumers carry it; cities-internet, gospel-resources and
my-upg-100-list boot maps another way and are not affected).
Also: the new Experimental bundle pplr-data-maps loads the Mapbox geocoder
under maplibre (pplrData.js:38). It is an owned, printed MAPBOX_KNOWN entry
routed to its owner; delete it in their fix commit.
