Class: InputFieldSystem

Drives InputFieldComponent. Runs in PreRender, after TransformSystem, so the DOM editor sits on this frame's transforms; label writes land before TextRenderSystem draws them.

Labels, every frame including edit mode: the text label shows the value (masked for Password / Pin), the placeholder label the placeholder while the value is empty. This system owns both labels' text and enabled — it hides them while the DOM element is up.

Focus: a tap on the field (pointer down → tap without dragging), or Focus(). One DOM element per kind (input / textarea) is reused and laid over the text label's screen quad each frame, rotation included. Typing writes text through its dirty setter. The edit ends on Enter (single line, submits), Esc (restores), a press anywhere else, the DOM losing focus, or the field going inactive / disabled / non-interactable.

Browser quirks handled here: a press's compatibility mousedown would move focus off the element right after a touch tap focused it, so the one after a press on a field is swallowed; key events stop at the element, so typing doesn't reach game input or host-page shortcuts.
