* M8: .fig import: a routed connector keeps its own empty paints and dash pattern

CodeRabbit review on #1813: an explicit empty strokePaints (no stroke) or
dashPattern (solid) on the connector no longer takes the generated record's.

Pages, artboards as frames with their background, groups; Sketch 2025 and newer: frames (clipping or not) with their style, graphics, stacks as auto layout (direction, gap, alignment, padding, wrap, hug/fill sizing, stretching filling every item across, items ignoring the stack), corners in the style (rounded, smooth with its smoothing; angled, inside square and inside arc as paths), pins and sizing, per-side borders, lists of blurs (progressive background blurs, glass), inner shadows in the shadow list, tints (a graphic's, group's or instance's fill colouring its layers, and colour overrides; from Sketch 64, before which a group's fill draws nothing), text colour and visibility overrides, text sized by its sizing; rectangles with corner radii, ovals, stars and polygons while their points are the generated ones, paths as editable vector networks, shape groups as their shape, as one compound path (children without an operation, by the group's winding rule) or as boolean operations (mixed operations nested from the left); operands' own borders ignored as Sketch does; open paths filled as if closed, edited ovals and rectangles as paths, bitmaps (their image under their style's fills; colour adjustments as image filters with Sketch's tone curve, contrast and then brightness added), slices, hotspots; transforms (rotation, flips after it), resizing constraints; fills (solid, gradients with Sketch's geometry, gradients mixed in OKLab or OKLCH as sRGB stops along the same colours, image patterns), borders (the first enabled border's width and position), shadows, inner shadows, layer, motion and background blurs (Sketch's radius is the standard deviation), opacity and blend modes; clipping masks (an outline mask that shows its own style draws a copy under itself, as Sketch does, and its opacity fades it and what it clips together; alpha masks only mask; broken mask chains wrapped), progressive opacity (Fade) as an alpha mask of its gradient; text with styled runs (UTF-16 ranges), paragraph and vertical alignment, lines placed by Sketch's line spacing behaviour, box sizing, fonts found by their PostScript names among the installed ones (else the family read from the name), variable font axes, Sketch's natural line (ascent and descent rounded, no line gap, a fifth more for classic Mac fonts) for text without a fixed line height; symbols as components (library copies on a page of their own) and instances carrying their masters' layers with overrides (text, nested swaps and hiding, images, also on shapes' image fills, layer and text styles, nested paths), clipping only where the master clips (`clippingBehavior` 1), laid out for their size the way Sketch does it (proportional sharing per pins from format 110, scaling before) and still live; master backgrounds in instances only when the master includes them in both instances and exports, as on Sketch's canvas and renders; Apple's system fonts found under the names designs use, with the platform's tracking kept as letter spacing; shared layer styles as paint (fills, border colours) and effect styles, shared text styles as text styles; Color Variables (also library ones) as colour variables with bindings; prototype links, flow starts, export options, layout and square grids (hidden, as Sketch shows them only in its layout view). Instances of a stack laid out at their size and texts an override changed measured again on open, an auto-width one growing from its aligned edge. Warnings: noise fills, OKLab and OKLCH gradients, motion and zoom blurs (drawn as plain blurs), fonts embedded with their data (not used), Smart Layout (kept as laid out), locked overrides, scaled instances.

 |---|---|---|
+| 2026-11-01 | patch | `.fig` and `.jam` import: a connector without a saved snapshot (elbowed and curved ones are routed here) took no stroke, so it was invisible (#1807); its line's paint, weight, cap and dashes now come from the file's generated line record, as a saved snapshot's do, and the connector's own values, when it has any, win. Test: `fig::connector_label_tests::a_routed_connector_takes_its_line_style_from_the_generated_record`. Numbers unchanged |
 | 2026-10-31 | patch | M4: Dash and Custom strokes have a Dash cap (None, Round, Square) in the advanced stroke settings and `node.set {dashCap}`, on both ends of every dash on the canvas and in PNG, PDF and SVG. Unset, dashes keep taking the end point caps, so older files look the same; the saved file writes it only when set. Numbers unchanged |
 | 2026-10-30 | minor | `.fig` import: a connector's label without a saved snapshot was skipped; now the connector imports as a frame holding its line and the label, as a connector with a saved snapshot does, the label centred on the line's middle by length (in a 200-wide box, laid out again with the fonts at hand), in the connector's fill paints or black. Its background isn't known without the snapshot and is left out. Not checked on real files. Test: `fig::tests::tail::a_labelled_connector_without_a_snapshot_keeps_its_label` |
 | 2026-10-30 | minor | Pasted content row: an image the clipboard doesn't carry keeps its name and shows a placeholder that reads as missing; the paste names those layers in its message and opens the import report with its notes (#1646). Numbers unchanged |
