Ygritteee/dsh-ygritte-boot

Full-screen ice-and-fire boot intro for DSH: a frost-to-ember boot sequence with typed bilingual logs and a hairline progress line, then Ygritte's five-step identity authorization. Esc skips, Enter or click fast-forwards, and a settings page switches it off/quick/full or replays it; the host half paints the opening frame while the document parses, so the built-in loading card never shows.
