The Shelves layer: where every box physically lives

Eric's spec, all nine points. Two committed local-only stores follow
the local_games.json pattern — furniture.json (units of openings with
interior dims; a dimensionless opening is a virtual spot like a travel
case) and locations.json (game key -> opening + note). Shelf layouts
are nobody's data but the owner's; nothing touches upload.

The Shelves page builds furniture without hand-editing JSON — the
acceptance bar (two double-wides above three rows of four cubes, two
bookcases, a travel case) is a TEST, driven entirely through the
endpoints the UI calls. Presets for Kallax/Billy/custom/virtual,
grid creation with A1-style labels, openings editable/deletable/
reorderable. Units render as grids: zone, count, fill bar (stacked
thinnest-axis vs interior height), ⚠ on overfull or any resident that
can't fit. Openings open as a modal — a bottom sheet at phone widths,
search-first with thumb-sized targets for the moving-day loop.
Unshelved games list alongside with one-tap suggestions (only openings
they verifiably fit, with room).

Containment composes: a game stored inside another box inherits its
container's location, rides along in the opening's resident list
(marked), and refuses direct assignment naming its container. The
detail page's where-it-lives card gains the picker (openings grouped
by unit, each labeled fits / doesn't fit / can't verify) plus virtual
notes ("lent to Sarah, June"); the Library list shows a location line,
filters by unit or unshelved, and search matches location text and
zones.

bggpipe dims drops its hardcoded Kallax for the user's actual
furniture: per-opening capacity, overfull and misfit warnings,
unshelved count. bggpipe shelve --import loads a name,opening CSV
(ids or labels), rejecting — never guessing — unknown names, ambiguous
copies, unknown/ambiguous openings, misfits, and contained games.

Ten new tests incl. the acceptance flow, inheritance, CSV rejects,
and a phone-sheet smoke; 372 total.
