 ## Progress log
 
+- **2026-11-09** · M1: the Page background reuses the Fill/Stroke/Selection colors paint field, including its responsive width, inline HEX, accessible swatch and fractional opacity. HEX retains the page alpha unless explicitly supplied; opacity scrubs remain one undo step. Regression coverage in `field_tests`. Sidebar audit: effect colours, layout-grid colours and prototype overlay backgrounds still have separate colour/opacity fields; prototype backgrounds, variable-action colours and selected-text Fill have colour-only custom controls. Numbers unchanged.
+
 - **2026-11-05** · M2, #1823: Suggest auto layout is its own command. `layout.suggest` used to run `layout.add` and made one row of everything. It now splits a frame's layers into rows or columns by the gaps between them, wraps each band of several layers in a hugging frame without fill and repeats inside it, so the design gets as many auto layout frames as it needs and keeps its placement where the gaps are even (the frame keeps its size). Uneven gaps, bands that start at different offsets across the flow (lined up at the smallest) and layers that overlap along both axes are reported as `warnings`, and instances and layers inside them are refused. `layout.add` is unchanged. Tests in `layout_suggest_tests.rs`. Numbers unchanged.
 - **2026-11-05** · M3, #2002: the Local variables window selects several variables with a click, Shift+click (range) and Cmd/Ctrl+click (toggle), cleared by Escape or a click on the empty space; delete, move to a group and scope act on the selected local variables as one undo step (`command.batch`); inherited variables can be selected but are left out, since they change in their own collection, and the bulk menu needs two or more local variables selected (otherwise the row shows its own menu). Rename and value edits stay single-row.
 - **2026-11-05** · M10, #2014: the desktop UI takes a system face for Ethiopic, Devanagari, Gurmukhi, Gujarati, Tamil, Telugu, Kannada and Malayalam, Sinhala, Lao, Myanmar, Khmer, Armenian and Georgian as it did for Hebrew and Arabic (`bidi::script_fallbacks`: one sample letter per script, the system's families for each; Bengali and Thai keep `crate::cjk`'s choice), so a layer name or a String variable's Amharic value draws in the panels instead of boxes. Test: `bidi::tests::other_scripts_take_an_installed_system_face`.

The picker's CSS field takes every CSS name too (`Color::from_hex_or_name`, `color::named`) |
 | Fields select their text on focus | done | Number and text values keep their vertical position when their editor gains focus (including typography spacing; `sidebar_field_text_stays_in_place_on_focus`). a click or Tab into a one-line field selects all of its text, so typing replaces the value: hex and colour fields, number fields, inline fields (a fill's hex, variable values, renames), names, search boxes and dialog fields; a drag from the press selects only what it covers; multi-line fields (descriptions, comments) keep the caret where clicked. The first click into an inline field (a fill's hex) now takes the keyboard; it took a second click. A rename (double-click, F2, File ▸ Rename, a page) selects the whole name before its field first draws, so a key typed in that same frame replaces the name; it was appended (`widgets::select_all_on_focus`, `select_all_tests`, `layers_rename_tests`) |
+| Page background colour control | done | Uses `widgets::paint_field`, as Fill, Stroke and Selection colors do: one background, inline HEX, accessible swatch toggling the picker and fractional opacity. Typed colours preserve alpha unless 4/8 HEX digits explicitly supply it; opacity scrubs remain live and undo as one step. Tests: `field_tests::the_page_background_opacity_field_sets_the_page_colour_alpha`, `field_tests::page_background_shows_fractional_opacity_like_fill_and_keeps_it_when_opening_the_picker`. |
 | Colour picker models | done | Hex, RGB, HSL, HSB, LCH, OKLCH and CSS; LCH and OKLCH keep lightness and hue when a colour leaves sRGB (chroma comes down); the values typed stay while the colour is theirs (a hue typed on a grey, a chroma sRGB can't hold); CSS reads `lch()` and `oklch()` with any hue unit and `none` (`figcraft_color::{Lch, Oklch}`). Values are the stored channels read as sRGB |
 | Colour picker placement and dismissal | done | Opens 8 pt beside the sidebar at the opening control, lifted to fit the screen; outside presses (including the sidebar), Escape and X close it. Reopening resets a dragged position; eyedropper sampling keeps it open, and so does a drag of the open gradient's handles or stops on the canvas (#1852). |
 | Colour picker image well | partial | the Image tab shows a checkered placeholder and Upload from computer until there is a file (no dialog at once); an image paint shows its asset preview; a file dropped on the open picker replaces the image, keeping the fill mode, crop, position and adjustments (`image.replace`). Layers' fills and strokes only (text ranges, styles and selection colours keep Upload). The Fill and Stroke swatches take no drop: a dragged file's position isn't known, so a drop with none goes to the open picker |

+## Sidebar colour control audit (2026-11-09)
+
+The Page background, Fill, Stroke and Selection colors reuse `widgets::paint_field`.
+The remaining custom controls are:
+
+| Control | Implementation | Remaining difference |
+|---|---|---|
+| Effects: drop/inner shadow and noise colours | `panels/right/effects.rs`, `fx_color` | Separate swatch, HEX and rounded opacity; colour-variable binding wraps the control. |
+| Layout-grid colour | `panels/right/effects.rs`, `grid_settings` | Separate painted swatch, HEX and rounded opacity; the swatch is not interactive. |
+| Prototype overlay background | `panels/proto_panel.rs`, `action_fields` | Separate swatch, HEX and rounded opacity; opacity scrubs apply only on release. |
+| Prototype device background | `panels/proto_panel.rs`, `settings` | Swatch and HEX only; no opacity field or picker routing. |
+| Prototype Set variable colour value | `panels/proto_editor.rs`, `literal_field` | Swatch and HEX only; no opacity field or picker routing. |
+| Selected-text Fill | `panels/right/paints.rs`, `range_fill` | Custom combined swatch/HEX row, with picker routing but no sidebar opacity field. |
+
+Device-colour presets and Developer Mode inspection swatches are display controls, so they
+are not colour/opacity editors. Variable cells and style editing live in separate windows.
+This audit records candidates for subsequent fixes; their behaviour is unchanged here.

 ## Revision history
 
 | Date | Change | Summary |
 |---|---|---|
+| 2026-11-09 | patch | M1: the Page background reuses the shared sidebar paint control; fractional opacity and picker toggling covered alongside alpha-aware HEX and scrub undo. Audited remaining custom sidebar colour controls. 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 |
 | 2026-11-02 | patch | M6, #1839: 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 by the nudge amounts (`tool.crosshair`), Enter places the object there (`tool.place`), Escape or a tool change takes it away; the canvas draws the crosshair and `ui.inspect` reports it (`tool.crosshair`), the Keyboard shortcuts panel lists the gesture ("Use the arrow keys to activate the crosshair cursor...", Accessibility at Figma). The board Shapes tool places on it too (its 160 px shape centred, as the tool centres a press), and the view pans by the overshoot when the crosshair is nudged past its edge. Tests: `place_crosshair_tests`, `shortcut_keys_tests::arrows_show_and_move_the_placement_crosshair_with_a_shape_tool`. |
