The grid now zooms, which needs thumbnails at two resolutions rather than
one, and exposed a scrub that landed in the wrong place.
**Two thumbnail size classes.** `ThumbSize::Grid` (256px, ~10 KB) and
`Large` (1024px, ~45 KB), with the class part of the store key so both
coexist. Storing everything large would take the reference library from
~200 MB to ~860 MB, and shards sync, so that is transfer cost on every
device rather than only disk. A store written before the class existed
migrates in place: its entries are all grid-sized, which is what the
column defaults to, so nothing already fetched is discarded.
`forget` now drops every size for an image. Reading a single row left the
other class's bytes on the shard's tally for good, sealing it early on
space nothing occupied.
**Grid zoom.** Ctrl+wheel and pinch resize cells between 90px and 420px in
geometric steps, so the gesture feels the same at either end where a fixed
pixel step would be imperceptible at 400px and violent at 90px. Crossing
256px switches to the large class, so a zoomed cell is sharp rather than
upscaled. Columns and window capacity already derived from cell size, so
the grid reflows for free.
**The scrub landed about half a library too high.** It counted only dated
images while the grid shows all of them — 10,733 dated against 19,841
rows — and ignored `shadowed_by`. Verified against the live catalog: the
old formula gave 10,887, the new one 10,732, the true grid position
10,732. The scrub's count and the grid's window must use identical
predicates and ordering; a test now fails if they diverge.
**Timeline gestures are continuous.** Scrub and pan were quantised to
whole buckets, so a slow drag did nothing until it crossed a boundary and
then jumped a month. Both work in fractions of the visible span now, and
pinch-to-zoom arrives for tablet, where there is no wheel to reach the
axis with.
The pinch accumulator was wrong on first writing: it took at most one step
per update, so an 8x spread — three doublings — yielded one zoom level.
`log2().trunc()` now extracts every whole doubling and carries the
remainder. The original test asserted the wrong number and defended it in
a comment, which is worth remembering: a test can entrench a bug as
readily as catch one.

The UI gains the views the catalog work was building toward: a windowed
library grid with ratings and flags, the collection tree with drag-to-add,
and trash with restore. derived_sync pushes thumbnail shards and the catalog
snapshot to the server's derived folder.
Tokens now have one source of truth. build.rs reads style.yaml and generates
theme.slint into OUT_DIR, which answers every existing
`import { Theme } from "theme.slint"` unchanged, because Slint resolves
imports against the importing file's directory first and the include paths
after. Generating into OUT_DIR rather than beside the hand-written Slint is
the point: a generated file sitting in ui/ looks exactly like the files
around it that are meant to be edited, and an edit to it would survive until
the next touch of style.yaml — a bug that hides for weeks. build.rs fails
loudly if a stale ui/theme.slint exists, which would otherwise shadow the
generated one silently and make every palette change vanish with no error.
The palette moves to near-neutral dark with achromatic signalling, so the
accent means "modified" or "active" rather than "heading". Shared components
land in widgets.slint: a token that binds several values into one concept is
a component, not a row in a YAML file.
Adds an optional live-style feature that makes the tokens in-out so they can
be written at startup — a feature rather than the default because it stops
the properties being constant-folded.
serde_norway is the YAML crate: serde_yaml and serde_yml are both deprecated,
and its mappings preserve insertion order, which is what lets the generated
Slint keep the token ordering the author chose.
