feat: bold Swiss/constructivist design overhaul

Typography:
- Inter for body text, Oswald for headings (bold condensed)
- ALL CAPS labels, large type hierarchy, tight letter-spacing

Colors:
- Black (#1a1a1a) background on UI elements, white text
- Red (#c62828) accent for hover states, underlines, CTA buttons
- Light gray (#f5f5f5) page background for contrast

Layout:
- Black nav bar with red bottom border, red hover states
- Red accent underline blocks (3px x 3rem) on page headings
- No border-radius anywhere — sharp rectangular constructivist forms
- Full-width 6-column gallery grid with 2px gaps

All pages redesigned: home, browse, upload, login, image detail,
and image viewer overlay.

feat: make tags clickable with usage counts, larger and more prominent

- Tags in ImageViewer and detail page are now clickable pill buttons
- Clicking a tag navigates to /browse?tag=<tagname>
  with the filter auto-applied on mount
- Browse page reads ?tag= URL param on initial load
- Tags display usage count badge (sorted most→least frequent)
- Larger pill sizing with hover effects in both viewer and detail page
- New GetImageTagsWithCounts DB function joins tags+image_tags
  for usage counts returned in GET /api/images/{id} as tags_detail

feat: make browse grid 6 columns and full-width

- Grid layout set to repeat(6, 1fr) with responsive breakpoints for smaller screens
- Removed layout max-width constraint on browse page via :global(main) override
- Header and pagination get their own padding within the full-width layout
- Increased per page to 60 for better coverage at 6 columns

feat: redesign browse grid with Chevereto-style card layout and hover overlay

- Compact grid with 2px gaps and dark image backgrounds (aspect-ratio 16:10)
- Image fills card via object-fit: cover with subtle scale-on-hover
- Gradient overlay on hover shows filename, dimensions, and truncated tags
- Removed rounded corners and info text below cards for cleaner look

feat: add image overlay viewer with keyboard navigation and idle UI fade

Replaces full-page navigation with a Chevereto-inspired lightbox overlay
when clicking thumbnails in the browse grid. Supports prev/next via
buttons and arrow keys, close via Esc/click-outside, auto-hiding controls
after 3s of inactivity, and a bottom info bar with metadata and download.

fix: preserve all tags on upload and return empty array on no match

Tags beyond the first were silently dropped because `r.FormValue("tags")`
returns only the first value when the frontend sends each tag as a
separate FormData field. Changed to `r.Form["tags"]`.

Nil slices in API responses (`var images []Image`) marshalled to JSON
`null`, causing a TypeError in the Svelte template (`null.length`),
making "Loading..." persist forever. Initialized all API-facing slices
with `make()` so they marshal as `[]`.

feat: implement core backend API and SvelteKit SPA

Full MVP implementation of the weimar media repository:
- CLI commands for user CRUD, image deletion, password reset
- HTTP API with auth (cookie sessions), upload, browse, download,
  thumbnail serving, and tag autocomplete
- SQLite-backed storage with migrations
- Hash-partitioned disk storage with EXIF stripping and thumbnails
- SvelteKit SPA with login, upload, browse grid, and image detail pages
- Makefile build flow: SvelteKit build -> Go embed -> single binary

feat: initial project scaffolding

Single-binary media repository for home servers — Go backend with
embedded SvelteKit SPA.

- Cobra CLI with viper config (TOML, env vars WEIMAR_*, flags)
- Commands: serve, users, image, version
- HTTP server with Go 1.22+ ServeMux, API route stubs, SPA fallback
- SvelteKit frontend with adapter-static (SPA mode, 5 routes)
- Build pipeline: Makefile, GoReleaser, UPX compression
- ldflags-based version and build date injection
