Add literate programming phase 1 documentation for: - main.sh: wrapper orchestration and user journey - config.sh: configuration management and defaults - sanity.sh: preflight safety checks Decision: UEFI-only support to reduce complexity. BIOS would require separate /boot partition and additional testing burden disproportionate to modern hardware usage. Decision: LUKS2 as default encryption for improved security tooling, with clear guidance for LUKS1 fallback if GRUB boot fails. Auto-detection rejected due to version fragmentation. Decision: Interactive configuration as default. Presets are out of scope for phase 1 to keep the flow understandable. The user journey documents the complete end-to-end flow from live medium boot to first encrypted boot, establishing clear handoff points between wrapper and installer.
