CalcMode repeats in every worksheet substream like the iteration records and sets wb.calc.mode from the first worksheet; CalcPrecision sits in the globals and sets precision_as_displayed, matching calcMode and fullPrecision on the .xlsx side.
CalcIter, CalcCount and CalcDelta repeat in every worksheet substream and were skipped, so a workbook saved with iterative calculation on opened with it off and its circular references showed #CIRC!. They now set wb.calc from the first worksheet, as <calcPr iterate iterateCount iterateDelta> does for .xlsx.
Brazilian Portuguese had 377 catalog entries, so most dialogs, menus and
tooltips showed in English with the interface set to Português (Brasil).
This adds every key the other catalogs translate (counting the open
Spanish-dialog #669, Russian #676, Czech #652, Polish #650, Turkish #663
and Italian #713 PRs), bringing pt-BR to 923 entries.

With two or more value fields the Σ Values pseudo-field can sit in Rows
as well as Columns, at any position among the row fields. The model
records it (`PivotTable.values_on_rows`, `values_position`) and the
engine lays it out like Excel in compact, outline and tabular form: one
row item per value field at the Σ Values level, per-value subtotals
("East Sum of Sales") and grand totals ("Total Sum of Sales").
XLSX reads `dataOnRows` and the `-2` field's place in rowFields or
colFields and writes them back; the "values on rows are shown on
columns" warning is gone. `pivot.moveField` moves "Σ Values" between
Rows and Columns or within one, axis field moves keep it in place, and
the PivotTable Fields pane lists it.

Each frame multiplied the whole-number zoom by egui's eased wheel
factor and rounded, so a notch out never undid a notch in:
100 -> 122 -> 101 -> 123 -> 102.
A notch now moves to the next step on WHEEL_ZOOM_LADDER (10 ... 85, 100,
120 ... 400; four per doubling, about 20% apart). A step less than 5%
away is skipped, but 100% and the limits never are, so 121% out goes
to 100% and 99% in goes to 100%. The wheel's turning is counted in
notches: parts of a notch add up, and a notch steps once 60% of it has
turned. With animations on the zoom glides to the step, and a notch
turned during a glide steps on from where it's going.
The status bar's Zoom In / Zoom Out keep their 10% steps; that, and
whether the glide needs a setting of its own, is noted in
docs/decisions.md for the maintainers.

Builds on the Solver of #327. data.solver takes reports: [answer, limits]
and writes them on new sheets before the model's sheet once a solution
is found. The Answer report lists the objective and variable cells with
their original and final values and each constraint's value, formula,
status (Binding or Not Binding) and slack; cells are named by the
nearest labels to their left and above. The Limits report minimises and
maximises each variable with the others held at the solution, under the
model's constraints, and gives the objective at both ends (Simplex LP
and GRG Nonlinear, without integer constraints).
data.solverReport writes the reports for a given solution and model,
so data.solver's result (which now carries the original values and the
model) can be passed to it as is. The Solver Results dialog offers the
two reports; they are written after Keep Solver Solution or Restore
Original Values.
Builds on the Solver of #327. method: evolutionary runs a genetic search
for models that aren't smooth: tournament selection, blend crossover and
Gaussian mutation inside the variable bounds, feasibility-first ranking
and integer rounding, then a compass search around the best member. It
stops when the population converges, when the best member stops
improving for a number of generations, or at the evaluation budget. A
seeded generator makes runs repeatable. Population size, mutation rate,
random seed, convergence and Require Bounds are options; the method and
its options are saved in the hidden solver_* names. The Solver
Parameters dialog offers the method.
The recent workbooks on the File view's Home and Open pages gain a
Modified column: "Just now", "5 min ago", "3 h ago", "Yesterday",
"4 days ago", "3 weeks ago", "5 months ago", "2 years ago", or
"Not available" for a file that can't be reached.
The file system is never asked while drawing. A thread asks for each
file's metadata and the list shows each answer as it comes back, so a
network drive that is asleep or a share that is away doesn't hold up
the view. One thread asks at a time; a view opened anew asks anew. Only
metadata is read: no workbook is opened until the user picks one.
The list tells ages rather than dates because the UI has no time zone
to tell a date by. From two days on a count is never one, so each
language needs one form of "days", "weeks", "months" and "years"; the
ten strings are in the nine catalogs, with the count placed by a {n}
in each, as "Page {page} of {pages}" does.
A long name or folder now stops short of the column instead of running
under it. The web build, which has no files to ask about, and a narrow
window show the list as before.

XLSX: strip _xlpm. from LET/LAMBDA parameters on read, keep line breaks in table columns, allow leading backslash in table names
# Conflicts:
# docs/file-format-parity.md
A `;`-separated CSV (the usual CSV where `,` is the decimal separator) was
rewritten with `,` on save: read_csv sniffed the delimiter but the result was
dropped, and save_bytes passed a hard-coded b','. file.save, Save As .csv,
file.exportCsv, file.saveBytes and gridcraft-cli convert all went through it.
The workbook now remembers the separator it was read with
(Workbook::csv_delimiter, set by read_csv) and a CSV save writes it back.
Workbooks not read from CSV, and .tsv/.txt sources saved as .csv, keep `,`.
Regression tests: `;`, `,` and tab .csv round trips byte for byte, new and
.xlsx-origin workbooks save with `,`, and open-by-path + edit + file.save on a
`;` file keeps `;` (also through exportCsv and saveBytes).

OK on the untouched field says the password is incorrect instead of
asking again; the Backstage closes once the workbook opens; app.open on
the control channel takes a password and never opens the dialog. Control
protocol docs cover file.open {password}.

Model: Series.trendlines (Vec<Trendline>, serde default) with kind
(linear, exponential, logarithmic, polynomial 2..6, power, moving
average 2..255), name, forward/backward forecast, set intercept,
equation / R² display and line colour, width and dash.
XLSX: read and write <c:trendline> in CT_Trendline child order, placed
after dLbls and before the data references in line, bar, area, scatter,
bubble and stock series; unknown types are skipped.
Chart: least-squares fits (transformed for exp/log/power, skipping
non-positive values; polynomials via normal equations on centred,
scaled x with partial pivoting), moving averages, forecasts that widen
the category or x axis, clipping to the plot, equation and R² labels and
legend entries ("Linear (Sales)"). Degenerate data draws nothing.
Engine: chart.addElement element="trendline" adds (type, series, order,
period, forward, backward, displayEquation, displayRSquared) or removes
trendlines; document.inspect lists each chart's trendlines.

Checked against Excel-cached TEXT() results in number- and text-format test workbooks: 226 of 352 TEXT cells mismatched before, 0 after.

Grouped rows and columns now get Excel's outline band beside the headers:
a bracket per group, a -/+ button on the summary line and level buttons
in the corner. The buttons run data.hideDetail / data.showDetail and the
new data.showLevels, so they undo. Hide Detail marks the summary line
collapsed, Show Detail keeps inner groups that were collapsed on their
own, and Group / Ungroup take by: rows|cols. Show Detail and Hide Detail
are on the Data tab and in the Data menu, the group shortcuts are listed
as Alt+Shift+Right / Left, and shortcut lookup reads navigation keys by
their logical key so the numpad arrows work.

wgpu's default DX12 compiler (Auto) loads the first dxcompiler.dll on the
DLL search path. GridCraft ships none, so another program's copy is used;
without a matching dxil.dll its 'DXIL signing library not found' warning
fails wgpu's internal compute pipelines, the device is lost and the app
exits before the first frame. Pin FXC (part of Windows) unless
WGPU_DX12_COMPILER asks for another compiler.
