Christopher Mühl 3d246c00ec chore: scaffold SvelteKit project with Capacitor and Tailwind 
- SvelteKit 2 (Svelte 5) with TypeScript, static adapter (SPA mode)
- Capacitor config for iOS/Android (so.toph.solidhaus)
- Tailwind CSS v4 via Vite plugin
- All dependencies: idb, nanoid, bwip-js, jspdf, Automerge, Solid
- Route stubs: dashboard, scan, items, locations, labels, settings
- Type definitions and ID generator utility
- Project specification and ontology files

# SolidHaus Ontology — Household Inventory Tracking
# =============================================================================
#
# Namespace: https://vocab.toph.so/solidhaus#
# Version: 0.1.0
# Author: Christopher (toph)
# Date: 2026-02-26
#
# This ontology extends schema.org types for household inventory tracking.
# It is designed to be used with Solid Pods for personal data storage.
#
# Key design decisions:
# - Reuses schema.org wherever possible
# - Adds tracking-specific properties not covered by schema.org
# - Location hierarchy uses schema:containedInPlace
# - Sighting events extend schema:FindAction
# - Actions follow schema.org Action vocabulary

# =============================================================================
# Classes — Check-In / Check-Out Model
# =============================================================================
#
# Items have a custody state: they are either "checked in" (stored at their
# designated location) or "checked out" (removed for use, lending, transport).
#
# This maps to schema:CheckInAction and schema:CheckOutAction, which exist
# in schema.org. We extend them with inventory-specific properties.
#
# The check-out reason captures *why* the item left storage:
# - in-use: actively being used (drill on workbench)
# - transit: being moved between locations
# - lent: lent to another person
# - repair: sent for repair/maintenance
# - temporary: temporarily relocated (e.g., for a project)
#
# Storage tiers capture *how accessible* the storage location is:
# - hot: immediately accessible (pegboard, desk, kitchen counter)
# - warm: in the room but requires effort (cabinet, toolbox, closed shelf)
# - cold: deep storage (attic box, basement bin, labeled container)
#
# The combination tells a rich story:
# "Drill is CHECKED OUT (in-use) from pegboard (hot) — at workbench"
# "Holiday lights are CHECKED IN at attic box #3 (cold)"
# "Borrowed book is CHECKED OUT (lent) from bookshelf (warm) — at neighbor's"
# =============================================================================

# Enumerations — Storage Tier
# =============================================================================
#
# Storage tiers describe how easily accessible a storage location is.
# This is crucial for the UX: when you're looking for something, it matters
# whether it's on the pegboard in front of you (hot) or buried in a box
# in the attic (cold). The tier affects both where you put things and
# how you find them.
#
# Tiers can be applied to:
# 1. A Place (the pegboard is inherently "hot" storage)
# 2. An Item's designated home (this drill's home tier is "hot")
