The office plan takes the phone's pixel ceiling too

`minimap.ts` is handed `deviceProfile().maxPixelRatio` and `officeMinimap.ts`
was not, so it defaulted to 2 and rendered a phone's floor plan at twice the
fill rate the city plan had already decided that handset could afford. Two 2D
canvases in one corner of one page disagreeing about what a phone is: exactly
the drift `deviceProfile` lives in a single file to prevent, and stage.ts says
so at the top. Mine to fix — it arrived with the plan two commits ago.
