Save as Web Page wrote only the cell table, so pictures and charts on a sheet
were dropped. A sheet that has either now keeps its own geometry and draws them:
- The table gets the sheet's column widths and row heights (`table-layout:fixed`,
a `<colgroup>`, a height per row); hidden columns and rows take no room and
merged-cell spans count only visible lines.
- A picture is an `<img>` with a `data:` URI, a chart is inline SVG built from
the chart crate's drawing primitives (titles, axes, legends and data labels
included), each absolutely positioned at its anchor cell plus offset.
- Sheets without pictures or charts write byte-identical HTML.
Adds contributors/people.toml entry for bilalmughal.
auto_row_height grew a row for every line break in a cell's text whether
or not the cell wrapped. Excel counts breaks only when Wrap Text is on:
with it off a multi-line value displays on one line and AutoFit gives a
one-line row. A file whose unwrapped cells hold pasted multi-line text
(the shape generating libraries write) opened with tall rows and nothing
visibly tall in them.
The fast path no longer treats a line break as a reason to measure, and
the measuring path lays text out over lines only for a wrapping cell.
Typing a break still turns wrap on (the Alt+Enter rule in cell entry) and
grows the row, as before.
Test: an unwrapped multi-line cell from a file keeps the default height
on open; wrap on grows the row; wrap off returns it; a typed break wraps
and grows. The open-time fit tests from #833 are unchanged.

`=1+` reported "unexpected `)`", although no `)` was typed: entry closes
missing parentheses by appending up to eight `)`, and when every retry
failed it reported the last retry's error. It now reports the error of
the formula as typed ("unexpected end of formula").
`gridcraft_formula::parse_closing_parens` holds the convenience and takes
the parse function, so cell entry and the UI's Spanish formula path share
it instead of each having its own loop.

along: =1+1+... with 4,096 operands (8,192 characters, exactly Excel's
limit, which Excel accepts and calculates) overflowed the stack when
entered, because the derived Clone of Expr recursed once per operand
down the chain's left spine. Saving hit the same in the XLSX writer.
- Expr: Clone, PartialEq, walk and map follow the left spine in a loop
and recurse only into right operands and real nesting.
- XLSX: _xlpm. prefixing and the implicit-intersection scan follow the
spine too. The scan's depth limit of 64 wrote any chain of more than
about 64 operands as a dynamic-array formula; such sums are plain
formulas again (ranges in the chain still get array evaluation).
- Evaluate Formula borrows sub-expressions instead of cloning each
operator's subtree (quadratic memory on a long chain).
- Spanish formula entry and display no longer refuse chains of more
than 256 operands; the left spine does not count as nesting.
Tests run on a 1 MiB stack (the Windows main thread) with Excel's
observed results: formula (clone/eq/walk/map/adjust at 4,096), calc
(401 and 4,096 operands, -, *, /, ^, &, %, comparisons, 1,500 refs),
xlsx (long chains written as scalar formulas), engine (cell.set, fill,
copy/paste, insert rows/columns, undo/redo, Evaluate Formula, XLSX save
and reopen), Spanish entry. Each fails without the fix.

Sheet names starting with '.' or reading as R1C1 (R, C, RC, R1C1...) were saved
unquoted, so Excel could not open the file; PivotTable sources and ADDRESS left
cell-like names (A1) bare. The quoting rule, unquoting and sheet splitting now
live once in gridcraft_core::addr and replace the copies in the formula printer,
pivot, ADDRESS, chart, xlsx, Solver, Go To and the Name Box (which now reads ''
as ').

iter_range walks the sparse store's bands for the area's row range
only, so a chain of N formulas no longer rescans every stored cell of
the sheet per area.

`SheetProtection` carries eleven permissions. `format_cells` is checked in
`apply_style`, and an edit to a locked cell is caught after the fact by
`check_protection`, but `sort` and `autofilter` had no reader anywhere outside
`sheet_read.rs`, `sheet_write.rs` and a round-trip test: they only ever
travelled through the file. So a protected sheet could still be sorted, and
Ctrl+Shift+L still put an AutoFilter on it.
`refuse_unless_allowed` sits beside `locked_cell_error`, with three call sites:
`do_sort` (which both Sort… and the A-to-Z buttons come through), `toggle_filter`
and `filter_by`.
Where the box decides is worth knowing. Sorting a range of locked cells was
already refused, by the locked-cell guard rather than the permission, because a
sort moves values between locked cells — which is Excel's rule too ("users
cannot sort ranges that contain locked cells on a protected worksheet,
regardless of this setting"). So the Sort box decides for a range that has been
unlocked, while an AutoFilter changes no cell's contents and the box is the only
thing that ever decided it. The test asserts both, and that an unprotected sheet
still sorts and filters.
Not fixed here: Delete Rows and Delete Columns are refused even when their boxes
are ticked, because deleting removes locked cells and trips the same post-hoc
guard, while Insert Rows and Insert Columns work. Letting the guard know which
operation ran is a change to code every command passes through and wants its own
PR.
It returned an empty string for every workbook, saved or not, so the classic
sheet-name formula `MID(CELL("filename",A1),FIND("]",…)+1,31)` gave #VALUE!:
with no `]` in the string there is nothing for FIND to find. Excel returns
`<folder>\[<file>]<sheet>`, and empty only before the first save.
The model had no file to report. `source_dir` could not serve: it names the
folder relative links to other workbooks are relative to, and must keep naming
it after a Save As into another folder, because the links held in memory are
still written for the old one — only the saved copy is rebased. `source_path`
is therefore its own field, with that distinction written down.
It is set when a workbook is opened, from the path made absolute so the folder
is the one the user sees, and when a full-fidelity save makes a file the
document's own — before the `saved` snapshot, or the workbook would read as
dirty the moment it was saved, and only when it changes, so an ordinary Save
does not clone the workbook for nothing. A workbook that arrived as bytes knows
its name but never a folder and reports `[name]Sheet`, which still splits on the
`]`; an import reports the file it came from, as Excel does. The sheet is the one
the reference is on, not the active one.
CELL is volatile and already in the volatile sets, so a cell holding it answers
from the next recalculation; after a Save As that means F9 rather than the save
itself, which the engine test asserts rather than papers over. Making a save
recalculate is a larger decision than this issue.
`check` still skips CELL("filename") as volatile, as docs/cli.md says: the
cached value in a file is the folder of the machine that saved it.
Bound the all-level walk to the sheet sparse cell store instead of
iterating every position of each precedent area: formulas late in a
wide area are no longer skipped, blank positions are never selected,
and only formula cells extend the frontier. Adds a regression test
(=SUM(A1:Z1) with a formula at Z1) and silences two clippy lints in
the same function.

Adds formulas.selectPrecedents / formulas.selectDependents engine commands
and binds them to Ctrl+[ and Ctrl+] (Ctrl+Shift walks every level), matching
Excel's shortcut parity. Direct-level traces keep whole precedent ranges;
cross-sheet precedents jump to the owning sheet; an empty trace leaves the
selection untouched with an actionable message.
Templates hide grouped columns as width="0" hidden="1". Show Detail and the level buttons only cleared hidden, so the columns stayed invisible; they now reset a zero size, as Unhide does.
The symbol was interpolated with Rust's Debug formatting, which escapes a
control character into literal `\n`-style text. It is now written into the
format's quoted literal directly, and a symbol holding a control character is
refused along with a quote or a backslash, so nothing is escaped behind the
user's back.
Test: `accounting_format_takes_the_symbol_it_is_given` covers `\n` and a tab.
`cargo xtask ci`: 8/8 steps, 0 failures.
`home.accounting` documents `{range?, symbol?}` but ignored the symbol: the
command always applied the `$` format, so a script or MCP client asking for
lempiras (#1893) or any other currency silently got dollars. The symbol is now
part of the code it writes, and a symbol that would break the format string (a
quote or a backslash) is refused instead of being pasted in. The default is
unchanged, character for character.
Tests: `accounting_format_takes_the_symbol_it_is_given` (displayed text for `L`
and the default, and the two refused symbols) and
`the_default_symbol_reproduces_the_accounting_format` (the built code still
equals the named `Accounting` format). `cargo xtask ci`: 8/8 steps, 0 failures.
range.fill parsed the input once at the active cell, then put back the old
style of every target that already held a cell, so 5%, $5, 3/4/2026 or
=DATE(...) lost their automatic format there (0.05, 5, 46085), and empty
targets took the active cell's style. Each target now gets what
input_to_cell gives for it (parsed once per distinct style), as typing does.

Undo stored the selection at the moment of undoing (wherever the user had
clicked) in the redo entry, so redo jumped back there instead of to the
cells it changed. The redo entry now keeps the undone step's selection.

file.open takes {csvAsText: true}: a CSV, TSV or TXT file opens with every field as the text
it holds, with no number, date or boolean conversion, so identifiers such as GTINs, SKUs and
ZIP codes keep their digits and leading zeros and save back unchanged. The default is
unchanged. The CsvOptions.parse_values switch already existed in the reader.

The grid's look() and print's cell_look() layered a rule's fill, font and
borders onto the cell style but not its num_fmt, so a cell under a rule with a
number format kept its own. Take the rule's code when it isn't General (in a
differential style General means "not set", as layer_under treats it).
Print also re-formatted every non-General cell from its own style through
display::cell_text; format with the look's code instead, through a new
display::value_text_as that value_text now calls (CSV/Text output unchanged).
Show Formulas keeps cell_text.

forecast_grid re-added every squared residual in each window, O(n×window).
Keep a running sum instead: add the entering term, subtract the leaving one,

auto_row_height estimated a line of a bigger font by scaling the sheet's
default row height by size / 11. When the sheet's default already fits
that font, the font counted twice: Excel for Mac saves rows of 16pt text
with defaultRowHeight="21" (28px) and no ht, and opening such a file
fitted every row to 40.7px, 1.45 times Excel's height. Rows mixing Middle
and Bottom aligned cells then looked misaligned.
The estimate now scales an 11pt row's height (DEFAULT_ROW_HEIGHT), so
those rows open at 29px, and rows on a 15pt-default sheet still grow to
their font (#833).

Checked black-box in Excel for Windows (Microsoft 365) with synthetic
workbooks: a bare name in <c:f> draws the whole chart blank, without a
repair prompt, for workbook- and sheet-scoped names alike, while
`[0]!Name` and `Sheet1!Name` plot.
- Write: a sheet-scoped name is written `Sheet!Name` (quoted when
needed) instead of bare; an already qualified name keeps its sheet;
an undefined name gets `[0]!`. A reference to an unknown sheet is
kept as written. A qualified series name is written as a strRef.
- Resolve: a series name `Sheet1!Name` is looked up on that sheet, as
the evaluator does, instead of being shown as literal text.

Excel writes a workbook-scoped defined name in a chart reference as
`[0]!Name`. The reader kept that text, the lexer took `[0]` for a
structured reference, and the series evaluated to #NAME?: a chart over
dynamic (OFFSET) names opened blank with one #NAME? category.
- Read: `[0]!Name` becomes `Name` in c:f (cat, val, xVal, yVal,
bubbleSize, tx), chartex cx:f and _xlchart names. External books
([1]Sheet1!...), quoted sheet names and strings are untouched.
- Write: a bare workbook-scoped name is written back as `[0]!Name`; a
sheet-scoped name stays bare. A series name that is a defined name is
written as a strRef instead of literal text.
- Resolve: a series name that is a defined name is evaluated.
