* Use chrono for UTC/calendar conversion instead of hand-rolled copies
Replaces the hand-rolled civil_from_days / civil copies and the hand-written
weekday / leap-year / days-in-month helpers with chrono. chrono is already a
workspace dependency (used by crates/text), so this reuses that entry and just
adds `chrono = { workspace = true }` to the engine and desktop app rather than
a second version.
- apps/deckcraft logging `timestamp` now formats through chrono (private
civil_from_days deleted).
- engine cmd::design `civil` (days since 1970 -> date, used for comment
timestamps in review.rs) uses chrono::NaiveDate.
- text datetime `DateTime::is_valid` / `weekday` use chrono::NaiveDate instead
of a hand-rolled leap-year table and days-since-1970 weekday.
Output is byte-identical and pinned by the existing logging, design and
datetime-field tests; each converted helper keeps a proleptic-Gregorian
fallback for dates outside chrono's NaiveDate range.
Follow-up to storytold/cadcraft#1785
* text: make chrono available on wasm32
is_valid/weekday in crates/text/src/datetime.rs use chrono unconditionally,
but chrono was only declared under the non-wasm target, so the crate (and
engine/pdf/render/ui-egui depending on it) failed the wasm32-unknown-unknown
check in `cargo xtask ci`.
- crates/text: declare chrono unconditionally (wasm-safe `std` baseline),
and keep `clock` in a separate cfg(not(target_arch="wasm32")) entry for
now_local()'s local clock, which is already wasm-gated to return None.
- workspace: drop `clock` from the shared chrono entry so it is no longer
forced onto wasm builds (engine uses chrono unconditionally too); `clock`
is now requested per-crate only where the local clock is read.
* Never panic on a clock outside chrono's range; harden the civil fallback
logging.rs timestamp(): chrono's From<SystemTime> unwraps, so a clock past
year 262143 panicked inside the logger. Use the fallible DateTime::from_timestamp
and read an out-of-range or pre-epoch clock as the epoch, as the old saturating
code did. Years past 9999 are written with {:04} like before, because %Y adds a
'+'. Tests cover both cases.
cmd/design.rs civil_fallback(): make the hand-rolled fallback's year arithmetic
saturating so civil() cannot overflow or panic at i64::MAX/MIN (the engine rule
forbids crashes and unchecked arithmetic). Behaviour is unchanged for every real
input; a test exercises both extremes. The output year is formatted with {y:04}
by review.rs, so no %Y prefix issue.
crates/text/src/datetime.rs: checked after review; is_valid already limited the
year to 1..=9999 before this PR, weekday() is only reached for valid dates, and
all its arithmetic is checked/euclidean, so no change is needed.
* Don't build an unrepresentable SystemTime in the far-future test
UNIX_EPOCH + Duration::from_secs(u64::MAX / 2) overflows Windows'
SystemTime and panicked before timestamp() ran, failing the Windows
test job. Build it with checked_add and only assert where it exists.
* Make civil() exact for every i64 instead of saturating
The out-of-range fallback saturated z + 719_468, so civil(i64::MAX)
returned a date 719,468 days early. civil() now has chrono convert the day
within its 400-year Gregorian cycle and adds whole cycles back as years
(i128 for the extremes), so the hand-rolled fallback is gone. Exact results
for i64::MAX/MIN and both sides of chrono's range are tested against Hinnant's formula.
* time: preserve out-of-range years in the log timestamp instead of the epoch
`DateTime::from_timestamp(..).unwrap_or_default()` changed the existing output: a
clock set far ahead (an input the old hand-rolled civil-from-days converted)
collapsed to `1970-01-01`. Restore the old conversion domain with a cycle-based
helper: reduce by whole 400-year Gregorian cycles (146_097 days), convert the
in-range remainder with chrono, and carry the year back as i128. Only the year
leaves chrono's range; month/day/time stay exact. Pre-1970 still clamps to the
epoch as before. chrono stays the only calendar logic (no new features).
apps/deckcraft logging.rs `timestamp` (SystemTime, u64 secs), pinned via a
platform-safe `UNIX_EPOCH.checked_add`:
u64::MAX/2 s → "292277026596-12-04T15:30:07.000Z" (was "1970-01-01..."),
10e12 s → "318857-05-20T17:46:40.000Z", 253_402_300_800 s → "10000-01-01...".
* Name the 400-year range extension as the one exception to the time rule
The rule said never to hand-roll calendar math, but the range fix
(shifting by whole 400-year Gregorian cycles so dates past chrono's year
range keep their old output) is cycle arithmetic, so the rule and the code
disagreed. The rule now names that exception: the library still computes
month, day and time, and only whole cycles are carried in the year.
* Say the library computes month and day; time-of-day is plain arithmetic
Narrows the range-extension wording: the date library computes the
calendar fields, and splitting seconds into hours, minutes and seconds
is ordinary arithmetic, which is what the code does.
PowerPoint for Mac lays out a table's text in the master's other-text
style (p:otherStyle), while shapes and text boxes take the presentation's
default text style (p:defaultTextStyle). A synthetic deck with an
otherStyle of 14 pt and a defaultTextStyle of 26 pt, exported as PDF,
draws a table cell at 14 pt and a shape's and a text box's text at 26 pt.
DeckCraft laid cells out through a stand-in shape that wasn't a table, so
they took the default text style: a deck whose two styles differ (18 and
20 pt) drew its table text 2 pt too large and wrapped its cells.
master_list_style sends text in a non-placeholder table to otherStyle,
and Shape::table_cell builds the stand-in every cell layout uses (drawing,
row heights, text placement, the caret and selection in a cell) as a
table. The table shape itself resolves the same way, so the formatting
state of a selected table reports the size its cells draw at.

The resize handles sit in the box's unflipped frame, so in a flipped box
(also one that a drag past the opposite edge just flipped) the dragged
handle is on the other side. Snapping looked at, and moved, the fixed
edge instead.

snap_resize ran snap_rect on the whole box, which looks at all three
edges on each axis and takes the nearest line. A fixed edge already on a
line (distance 0) always won, so the dragged edge never snapped; a fixed
edge near a line moved the dragged edge by its own distance. Resizing now
looks only at the dragged edges (snap_edges), also for the grid fallback.

A shape added after an Undo can get an undone copy's id; duplicating it then
used the move measured from the old original.

Duplicating a shape, moving the copy and duplicating that copy again places
the next copy the same distance further on. Anything else, an undone copy or
another slide gets the usual offset.

An overflow to infinity (move x=1e308 dx=1e308) now lands on the limit
instead of resetting to 0, and a rotated shape re-centred after a capped
resize stays within POS_LIMIT (CodeRabbit review).

recovery::instance_id() mixed std::process::id() into the instance hash —
on wasm32-unknown-unknown that panics (``no pids on this platform``, and
SystemTime is missing too), so the web app died before its first frame.
On wasm the browser clock (js_sys::Date::now(), already an engine dep for
comment timestamps) stands in.
