• PDF Size-Aware Rendering — UIImage(pdfData:preserveTransparency:) now accepts an optional size: CGSize? parameter. When provided (and non-zero), the PDF is rendered at exactly that logical size using the current screen's retina scale, producing crisp HiDPI output. When omitted, the existing behaviour (native PDF size capped at 4096 physical pixels) is preserved. Call sites in DeltaSkin.image(for:) pass rep.mappingSize so skin images are rendered at the correct display resolution.
• Per-button Sprite States — Skin buttons in info.json can now declare a states block (Manic EMU format) with normal and pressed image references. The new DeltaSkinButtonStates, DeltaSkinButtonStateImage, and DeltaSkinButtonAnimated model types are decoded from the skin ZIP and stored on DeltaSkinButton. DeltaSkinView loads and caches per-button normal/pressed images, preferring the typed states field over the legacy raw-JSON asset dictionary
