The old kit read Input.mouse_x() * gl_scale; ludic.ui read it raw against a layout sized in
drawable pixels. A backend says how many screen pixels one pointer unit is (pointer_scale);
render3d's is gl_pixel_scale(), 1 on Windows and headless.

A game no longer writes a host:
- The runtime reads Input itself: focus and keyboard navigation (Tab, arrows, Enter/Space,
autofocus), the pointer (hover, :active, click on release, drag), and scroll boxes with the
wheel, a draggable scrollbar, clipping and scroll-into-view.
- HTML's controls are built in (button, checkbox, radio, range, select, text, key capture), made
of plain parts a stylesheet styles, each reporting with on-change and event.value.
- ludic.ui/render3d.ludic draws with render3d's overlay: textures, named atlases (icon:NAME),
nine-slice border-image, rounded rects and rings, clipping, and a scale.
- Hooks for the program's language, sounds and clock (ui_translator, ui_sounds, ui_clock).
- ui_dev: hot reload, errors on screen, LUDIC_UI_DUMP.
- CSS:
- colours as #rgb / #rrggbbaa / rgb() / rgba() / names;
- border-radius and outline (following the radius), box-shadow, background-image and a tinted
border-image;
- group opacity, @keyframes / animation, transition;
- :focus, :focus-visible and :focus-within.
- HTML mixed content, and boolean attributes.
- render3d gains tex_width / tex_height, and the XML reader keeps text runs in order.
