value toggle, and redesigned constraint-ribbon icons
Properties panel:
- New "Parameters" section (shown with no selection) listing every named
parameter with inline name/formula editing, add, and delete, backed by
new PropValue::ParamRow/ParamAddRow and command_driver handlers
(resolve_named_parameter_edit, on_prop_param_commit/_delete/_add_new).
A fresh parameter's formula now defaults to "1", not "0" — a 0-length
seed value is a genuine solver singularity for a Distance constraint
driven by that parameter, with no defined direction to grow back out of.
- New "Constraints" section (shown for a single selected entity) listing
every constraint touching it as a clickable PropValue::EntityLink that
selects the linked entities in the viewport, danger-tinted when the
constraint conflicts.
Constraint pills:
- New Options > General toggle, "Show values and parameter names on
constraint markers" (on by default, persisted). Off, every pill shows
just its bare glyph instead of glyph+driven-value/parameter-name — the
glyph alone is enough to see a constraint is present, without the value
text covering nearby geometry on a dense sketch.
Constraint-ribbon icons:
- Replaced all 18 unicode/letter glyph icons (including the plain "F",
"L", "M", "S" letters) with proper SVGs under assets/icons/constrain/,
matching the Modify section's two-color style (#B4B6B9 white / #6DB7ED
blue, consistent stroke width). Tangent reuses the Draw section's
white-arc-plus-blue-dots motif.

Add MTP (Midpoint Between Two Points) as a keyword that can be typed
during any point-picking command (e.g. LINE) to suspend the current
command, prompt for two points, and return the midpoint to the parent.
- New Mid2PointCommand registered under both "MTP" and "M2P" aliases
- ReturnPoint CmdResult variant feeds the resolved midpoint back to
the suspended parent command
- MTP/M2P typed during a point step suspends the active command and
starts the midpoint modifier; Escape restores the parent command
- Preview wires show a rubber-band line with a triangle marker at
the midpoint
- Character-by-character typing is routed correctly even with dynamic
input active (digits no longer leak into dyn fields)
- Three automation tests cover the full workflow, ESC restoration, and
dynamic-input character routing
