Evangelion-inspired theme plugin for DSH WebUI

Key features

• Three switchable schemes, all dark, each with a complete --dsw- token set (86 tokens) so all elements re-tint on switch — surfaces, labels, buttons, states, bubbles, input bar, sidebar, scrollbars, code blocks, menus
• Unit wallpaper backdrop per scheme (embedded data URIs
• wallhaven fan art, no baked-in text/watermarks), painted right of center behind the app with a left-side protection gradient so the chat column stays legible while the artwork shows through the translucent panels.
• Sidebar switcher (wide)a mecha art banner for the active unit plus three unit buttons, injected into the sidebar's sidebar.footer.action slot
• collapsed rail mode shows three unit dots.
