/* |
| 37 |
* Desktop-theme corner ornaments (WINDOW_CORNER_{NE,NW,SE,SW} |
| 38 |
* texture slots). |
| 39 |
* |
| 40 |
* ## Why they are INSET rather than centred on the handle |
| 41 |
* |
| 42 |
* The obvious placement — centre the ornament on the resize handle — |
| 43 |
* is wrong, and looks it. `.os-window` sets |
| 44 |
* `overflow: hidden` (it clips iframe content to the rounded |
| 45 |
* corners), and the handles deliberately sit 3px OUTSIDE the window |
| 46 |
* box so an edge-grab still lands. So a handle-centred ornament gets |
| 47 |
* clipped twice: the part past the window edge is cut, and then |
| 48 |
* `border-radius` shaves what remains. The result reads as if the |
| 49 |
* artwork were painted behind the window. |
| 50 |
* |
| 51 |
* Escaping the clip is not an option worth its cost: the ornaments |
| 52 |
* would have to leave `.os-window` entirely — a wrapper |
| 53 |
* element, or an overlay in `.os-area` whose geometry is |
| 54 |
* re-tracked on every drag/resize frame. A theme that genuinely |
| 55 |
* wants artwork OUTSIDE the frame already has the right tool in the |
| 56 |
* `WINDOW_FRAME` slot: `border-image` paints in the border area, |
| 57 |
* which `overflow` does not clip. |
| 58 |
* |
| 59 |
* So the ornament is anchored inside the window's rounded corner |
| 60 |
* instead. The default inset clears the handle's 3px overhang plus a |
| 61 |
* share of the corner radius, which is what keeps the arc from |
| 62 |
* cutting it at larger radii. Themes that want it tighter or looser |
| 63 |
* override `--os-window-corner-inset`. |
| 64 |
* |
| 65 |
* Physical `top`/`left`/`right`/`bottom` rather than logical |
| 66 |
* properties here, deliberately: these track the resize handles, |
| 67 |
* which are physical corners by nature (the NW handle is top-left in |
| 68 |
* both LTR and RTL) and are themselves positioned physically. |
| 69 |
* |
| 70 |
* With no theme active every `--os-window-corner-*-image` |
| 71 |
* is unset, the shorthand resolves to `none`, and the pseudo-element |
| 72 |
* paints nothing — zero visual change and no image request. |
| 73 |
* |
| 74 |
* NOTE the BEM modifiers are `--ne` / `--nw` / `--se` / `--sw` on |
| 75 |
* `.os-window__resize-handle`, not bare `.--ne`. |
