Sort-Derived Grouping And Calmer Metadata

Folder contents and search results use the active Sort choice to create visible sections in both List and Grid. Grouping is not a second preference and cannot contradict the selected ordering.

The initial Sort for users without a stored preference is Newest. Existing stored Sort choices remain unchanged.

Directories remain first in one Folders section because directory sizes are not available and directory modified dates are often misleading. The active Sort still orders directories inside that section.

Files use these groups:

Items remain ordered by the active Sort inside their derived section. An unknown date or size has an explicit fallback group.

Ordinary files show size as their single supporting value. Date moves to the section heading, avoiding the same date on every item. Directories do not repeat a Folder supporting label.

Grid retains two filename lines because generated camera and screenshot names often share a long prefix. Every Grid filename reserves two lines so neighboring tiles align even when one name is short. List and Grid reserve enough trailing scroll space for the create-folder action.

Recursive search results continue to show In <location> instead of size when location context is needed. The same sort-derived section model is used for normal browsing, current-folder search, and recursive search.

Sort remains a global persisted preference. Per-folder Sort memory and density are still deferred. Thumbnail decoding and crop behavior are unchanged by this polish.

Unit coverage fixes locale, time zone, current time, threshold values, direction, unknown metadata, type aliases, and the Folders exception. Build verification covers unit tests, lint, and a debug APK. Device checks cover List/Grid section headers, Sort changes, calmer metadata, search results, selection, and final-row clearance above the floating action.
