Unit fields and length strings read a percentage operand as a share of
a value. After * or /, the percentage scales the term before it:
3cm*50% is 1.5 cm and 3cm/50% is 6 cm. After + or -, it adds or takes
away that share of everything before it: 50pt+25% is 62.5 pt and
100pt+20pt-50% is 60 pt. Before this change these expressions read as
nothing, and the field kept its old value.
The parser now splits a sum at its last + or -, so a percentage applies
to the whole sum before it. Text without % gives the same values as
before, apart from float rounding. A percentage on its own (50%) still
reads as nothing, and percent and degree fields still read % as their
suffix.
Command length strings use the same parser: file.new's width and
height, the distance params and the length preferences.

- The pt ladder stays 0.25 … 10, 20, 30 … 100 pt (the dropdown's documented 20/30/40 pt steps).
- Feet, yards and meters returned the pt ladder converted as if it were in that unit (a 100 m
stroke); they now get the pt ladder in points.
- weight_presets returns a fixed array (no allocation per frame); the pica ladder is stored in
points; 0.325 in is 0.375 in (the eighths ladder).
- Fields keep three decimals in points, pixels and picas (595.276 pt) and show four in mm, cm,
inches and larger units (8.2677 in, 0.0078 in).
- ROADMAP: the Stroke panel's per-unit presets.

The Stroke panel weight dropdown converted one pt-based preset list into
whatever Units > Stroke was set to, which produced ugly rounded values like
0.088 mm, 0.265 mm, 10.583 mm from the pt ladder. Each unit now has its own
native ladder (observed from Illustrator's running dropdowns and typed in),
converted to pt once at use. Points, Millimeters, Centimeters, Inches,
Pixels and Picas each get Illustrator's actual values; the exotic Unit
variants (Feet & Inches, Meters, Yards, Feet) fall back to the pt ladder.
Picas round-trip to exact pt weights (1 pt, 12 pt, 60 pt …) but display as
decimal picas until Unit::number learns 0p1 / 1p3 notation; that is a
system-wide formatter change left for a separate PR.
Also bumps Unit::number precision from 3 to 4 decimals so Illustrator's
sub-eighth-inch strokes (0.0078, 0.0156, 0.0313, 0.0625 in) show their
authored values instead of rounding to 0.008 / 0.016 / 0.031 / 0.063.
Trailing zeros are still trimmed, so 1 pt stays "1".

The General unit is the active document's units: Preferences > Units >
General sets them (one undo step) and is the units new documents start
in (and the unit shown with no document open); Document Setup changes
only the document. The Transform panel, Properties, the Control bar, the
Info panel, rulers, the status bar, Align spacing, Tabs, paragraph
indents, Pattern Options, dialog distances (Move, shape sizes, path
dialogs, Artboard Options, effect distances, Transform Each, parameter
dialogs), New Document and the canvas measurement labels (smart-guide
sizes, moves, the Measure tool, the Live Corners radius) all follow it,
live. Units > Type drives font size, leading and baseline shift; Units >
Stroke also reaches the Appearance panel and the Magic Wand weight
tolerance. Typed units ("5 mm", "12 pt") work in any field; all ten
units are choices; length preferences show in their unit and accept a
unit; offset/simplify/grid/type-size params read typed units. Typed text
starting with a multi-byte character no longer panics the parser.
