The chosen view is published at /, the other under /timeline/ or
/grid/. Page paths, pager links and the cross-links between the views
are derived from the setting. The directory named after the default
view is removed on build, since it can only be a leftover from before
a switch.

Each timeline date heading now links to /day/<YYYY-MM-DD>/, a page
holding just that day's photos with a back link to the timeline.
renderDayPages writes one per groupByDay run; the ISO label doubles
as the URL slug.
