M5: Locked layers follow Figma's rules: no nudge, a locked parent's children stay locked (#1560) (#2219)

* M5: Locked layers follow Figma's rules: no nudge, a locked parent's children stay locked (#1560)

Pins Figma's locked-layer behaviour (measured in Figma's web app, 2026-11-10; help center "Lock and unlock layers") in a new lock_behaviour_tests suite. Fixes the divergences: transform.nudge and transform.nudgeSize skip locked layers, object.toggleLock without a value counts a child of a locked parent as locked (so it never locks the child on its own), and the Layers panel padlock on such a child is inert.

* Layers panel: a padlock sweep skips the children of a locked layer (#1560)

A padlock drag sweep no longer collects rows with `locked_above`, so
dragging across a locked frame's children leaves their own flags alone
and draws no swept value on them. An eye sweep is unchanged.

* M5: Lock/Unlock leaves a locked layer's child alone in a mixed selection (#1560)

With a locked frame's child and an unlocked layer selected, Lock/Unlock set both own flags, so
the child stayed locked once the frame was unlocked. With no explicit `locked` value, the command
now skips a layer whose parent is locked, as its padlock does; an explicit value (scripts) still
sets it.

pick select: Tab while the keyboard selection box shows (or the chord again) puts a pink outline on a layer and the keys walk the layer tree from it, as Accessibility at Figma says (#1836); scrubbing a field faster or slower by the pointer's height, with a notice of the speed, as the help center's Scrub fields says (#1837); component rows in the Layers panel at AA contrast in the theme's component tint, with the rows inside a selected component in a tone of its row (#1903); Cmd/Ctrl-click on a padding field sets all four sides with the value typed, a documented auto layout shortcut;

a number field scrubs when dragged with Alt held, as the help center's scrub section says, not only by its label; reuse visible layer selection roots (M8); ; with a shape or frame tool chosen and nothing selected, the arrows show a placement crosshair in the middle of the view and move it, and Enter places there, as Accessibility at Figma says (#1839); text direction per paragraph: Text ▸ Text direction forces a paragraph left to right or right to left, as Add right-to-left text says (#1830), with `text.direction`, `node.set textDirection`, the Type settings control once a right-to-left script is in the text, inspect, the CSS `direction` and the `.fig` lines' `sourceDirectionality`; the boolean operation menu in the Design panel leads each entry with an original icon drawn in code, a filled preview of the result (#2003); a press on the open gradient's handles or stops on the canvas keeps the colour picker open through the drag, as its own control (#1852); a click with the Bend tool on a sharp point curves it, its handles along the line between its neighbours, as Edit vector layers says (#1875); wrap style: Auto, Balance and Pretty on a text layer decide where its lines break, as Explore text properties says (#1827), with the Type settings control, `text.wrapStyle`, `node.set wrapStyle`, inspect and the CSS `text-wrap`; Backspace or Delete at the start of a list item keeps the item's indentation level, as the lists article says; max lines on auto-width text keep it auto width, hugging that many lines, as the text properties article says; superscript and subscript are synthesised where the font has no glyphs for them, from the standard glyphs shrunk and shifted by the font's OS/2 metrics, and a run mixing available and unavailable glyphs is synthesised whole, as Explore text properties says (#1828); Alt+Enter while editing text opens the link at the caret, as the accessibility page documents; Minimize, by its shortcut or the button by the file name, collapses the navigation bar and both sidebars as the help center says, with the right sidebar back while something is selected (#1835); the interface size keys of the help center's accessibility page: Cmd/Ctrl+Shift+Alt with =, - and 0 step the interface through the Preferences sizes and back to the system's size; Cmd/Ctrl+Alt+arrows rotate the selection a degree at a time, 15 with Shift, as the help center's accessibility page says; they resized before; the Layers panel answers Ctrl+1 as well as Alt+1 on Windows and Linux, the two keys the help center gives it; the colour picker's Image tab shows a placeholder and Upload from computer, an asset preview, and a file dropped on it replaces the image, keeping the fill mode, crop and position (#1682); the keyboard's Menu key opens the context menu, as Shift+F10 does; the eyedropper with Cmd/Ctrl+Shift makes a colour style or variable of what it picks; sidebar number and text fields keep their text vertically centered when focused, including typography spacing; with the pen out, Enter or a double-click ends the path and edits the vector with the Move tool instead of drawing on (#1430); the Actions palette offers only commands that run from it, and no second row reading like a menu item: Place image opens the file dialog (#1574); Preferences ▸ Scroll wheel zoom: a mouse wheel zooms the canvas about the pointer and Cmd/Ctrl+wheel scrolls (#1390); boolean operations refuse input past their caps, and a boolean group past them draws without its result (#1104); the selection and hover outlines of rounded rectangles and frames follow their corners (#1506); colour picker review fixes for text undo, fitted sidebars, moving controls and gradient variables; Corner smoothing: an original icon andLine truncated

scrubbing a field faster or slower by the pointer's height, with a notice of the speed, as the help center's Scrub fields says (#1837); component rows in the Layers panel at AA contrast in the theme's component tint, with the rows inside a selected component in a tone of its row (#1903); Cmd/Ctrl-click on a padding field sets all four sides with the value typed, a documented auto layout shortcut; a fill per region of a vector: with regions selected in edit mode, the Fill section and the fill commands edit those regions' own fills, as Edit vector layers says (#1875); the Fill section of a text whose characters were coloured differently while editing shows mixed content, characters that all share fills the layer doesn't have show those, and a layer-level fill edit reaches every character (#1856); a number field scrubs when dragged with Alt held, as the help center's scrub section says, not only by its label; reuse visible layer selection roots (M8); ; with a shape or frame tool chosen and nothing selected, the arrows show a placement crosshair in the middle of the view and move it, and Enter places there, as Accessibility at Figma says (#1839); text direction per paragraph: Text ▸ Text direction forces a paragraph left to right or right to left, as Add right-to-left text says (#1830), with `text.direction`, `node.set textDirection`, the Type settings control once a right-to-left script is in the text, inspect, the CSS `direction` and the `.fig` lines' `sourceDirectionality`; the boolean operation menu in the Design panel leads each entry with an original icon drawn in code, a filled preview of the result (#2003); a press on the open gradient's handles or stops on the canvas keeps the colour picker open through the drag, as its own control (#1852); a click with the Bend tool on a sharp point curves it, its handles along the line between its neighbours, as Edit vector layers says (#1875); wrap style: Auto, Balance and Pretty on a text layer decide where its lines break, as Explore text properties says (#1827), with the Type settings control, `text.wrapStyle`, `node.set wrapStyle`, inspect and the CSS `text-wrap`; Backspace or Delete at the start of a list item keeps the item's indentation level, as the lists article says; max lines on auto-width text keep it auto width, hugging that many lines, as the text properties article says; superscript and subscript are synthesised where the font has no glyphs for them, from the standard glyphs shrunk and shifted by the font's OS/2 metrics, and a run mixing available and unavailable glyphs is synthesised whole, as Explore text properties says (#1828); Alt+Enter while editing text opens the link at the caret, as the accessibility page documents; Minimize, by its shortcut or the button by the file name, collapses the navigation bar and both sidebars as the help center says, with the right sidebar back while something is selected (#1835); the interface size keys of the help center's accessibility page: Cmd/Ctrl+Shift+Alt with =, - and 0 step the interface through the Preferences sizes and back to the system's size; Cmd/Ctrl+Alt+arrows rotate the selection a degree at a time, 15 with Shift, as the help center's accessibility page says; they resized before; the Layers panel answers Ctrl+1 as well as Alt+1 on Windows and Linux, the two keys the help center gives it; the colour picker's Image tab shows a placeholder and Upload from computer, an asset preview, and a file dropped on it replaces the image, keeping the fill mode, crop and position (#1682); the keyboard's Menu key opens the context menu, as Shift+F10 does; the eyedropper with Cmd/Ctrl+Shift makes a colour style or variable of what it picks; sidebar number and text fields keep their text vertically centered when focused, including typography spacing; with the pen out, Enter or a double-click ends the path and edits the vector with the Move tool instead of drawing on (#1430); the Actions palette offers only commands that run from it, and no second row reading like a menu item: Place image opens the file dialog (#1574); Preferences ▸ Scroll wheel zoom: a mouse wheel zooms the canvas about the pointer and Cmd/Ctrl+wheel scrolls (#1390); boolean operations refuse input past their caps, and a boolean group past them draws without its result (#1104); the selection and hover outlines of rounded rectangles and frames follow their corners (#1506); colour picker review fixes for tLine truncated

+| 2026-11-10 | patch | M5, #1560: locked layers follow Figma's rules (Lock and unlock layers; measured in Figma's web app): a locked layer selected in the Layers panel ignores the arrow keys and the nudge commands while its properties still edit, and a child of a locked layer keeps its padlock inert (the Layers panel padlock, Lock/Unlock and `object.toggleLock` without a value no longer lock the child on its own) |
 | 2026-11-10 | patch | #2217: the main menu's submenus (Object, say) ran past the window's bottom, behind the taskbar, with the lowest commands out of reach, because submenus were not constrained to the window (to keep them beside their row). Every menu panel now scrolls when taller than the window less 8 pt margins, and a submenu is held within the window's height (moved up, never above the top) while keeping its place beside its row, so menu-aim is unchanged. Tests: `menu_overflow_tests.rs`. Numbers unchanged. |
 | 2026-11-02 | patch | Shortcuts: a Cmd/Ctrl-click on a padding field (the horizontal or vertical pair, or a side with Individual padding open) makes the value typed go to all four sides, in one undo step (Guide to auto layout, Keyboard shortcut guide); a plain click still edits that axis or side alone. A documented gesture row: 134 documented, 133 bound. Test: `padding_individual_tests` |
 | 2026-11-01 | patch | Number fields: dragging the field itself with Alt held scrubs it ("You can also hover the input field itself and hold down the modifier key: Mac: ⌥ Option Windows: Alt", Adjust alignment, rotation, position, and dimensions), with the resize cursor and the label's rates (Alt is the enabler there, so it isn't the fine rate); a click with Alt doesn't open the editor. Found by a documentation audit of the ui-parity rows. Test: `field_tests::alt_held_over_a_field_scrubs_it`. Counts unchanged |
