The Driver asked for full-screen, and for "a print that stays sharp when
zoomed".
Full screen. The planner mounts the shared FullscreenButton (the library's
Fullscreen-API control, with its CSS pseudo-fullscreen fallback for iOS
Safari) as a map overlay. It full-screens the whole planner, toolbar and
map, not just the canvas. Measured from a 520px embed in the Research
Gallery on a foreign page: the planner took 1280x800 and the map grew 459
→ 739px. The label is translated (Arabic "تبديل ملء الشاشة"), because the
planner now keeps the shared vue-i18n instance on its own locale. Before,
Share and Full screen took the PAGE language even when the gallery sent
another.
Print resolution, measured, not asserted. The printed map lays out at
7.53 x 8.4 in on the letter sheet (printable width = 8.5in minus the two
12mm margins; emulateMedia alone does not apply @page margins, which
misread it once as 8.48in). Its image is 2400x2688 px, so 319 x 320 DPI.
A 1:1 crop of the zoomed print was read: small street names (Sancaktar
Yokuşu Sokağı, Baki Dede Sokağı), individual building outlines and
footpaths are crisp, because the map is rendered from vector tiles at
pixelRatio 2, not upscaled from the screen. One PDF page.
check:prayer-walk-planner gains both: full screen from a 520px embed must
take the viewport, and the printed map must measure >= 300 DPI. 10/10
PASS.
