M4: UI parity doc: a sharp point whose far ends coincide keeps the old behaviour (#2110)

The revision row now lists A = C (zero direction) among the cases
smooth_sharp_point leaves alone.

| Date | Change | Summary |
|---|---|---|
| 2026-11-11 | patch | M4, #2110: in vector edit mode, choosing Mirror angle or Mirror angle and length for a sharp point (two segments, no handles) makes it smooth, as measured in Figma: both handles on one line through the point, along `(B - A) / \|BA\|^2 + (C - B) / \|BC\|^2` (A and C the far ends of its segments), each 0.3905 x its own segment for angle, both 0.3905 x the shorter segment for angle and length (the factor is known to about three digits; the length rule is medium confidence); several selected points each become smooth. Open-path ends, points that already have a handle, and points with a coincident neighbour keep the old behaviour. Evidence: tests in `crates/engine/src/canvas/vectoredit/ops.rs` and `tests.rs` |

Open-path ends, points that already have a handle, points with a coincident neighbour, and points whose two far ends coincide (A = C, so the direction is zero) keep the old behaviour. Evidence: tests in `crates/engine/src/canvas/vectoredit/ops.rs` and `tests.rs` |
| 2026-11-07 | patch | Transform: Shift while rotating lands on absolute multiples of 15°, measured in Figma (a layer at 7° or -4.27° Shift-rotated by its corner ends at 15°); FigCraft rounded the turn since the drag began, so 7° landed on 7 + k*15. The gesture keeps the selection's shared rotation and rounds base + turn; a selection with different rotations keeps rounding the turn. Test: `shift_rotating_lands_on_multiples_of_15_not_steps_from_the_start` |
| 2026-11-10 | patch | M1 review follow-up: strengthen canvas alpha, clipping/coverage, grid geometry/order and drawn-theme tests; use settled fresh sidebars at each width, check HEX visibility and opacity alignment, and assert picker toggling preserves page alpha. Production behavior unchanged. |
| 2026-11-09 | patch | M1: canvas page transparency uses a checkerboard that follows light/dark themes and applies background alpha once, including partial or missing renders. The page control also fits both sidebar width limits. Tests: `canvas::background::tests`, `field_tests::page_background_colour_and_opacity_fit_a_resized_sidebar`. Numbers unchanged |
