The shipped boot art was a fixed navy that vanished against dark theme bases. Recolor each element from theme-state.json at build time (flat fill, alpha preserved): foreground glyphs (logo, padlock, password dots) → text, the field/track boxes (entry, progress_box) → surface, and the progress fill → accent. text/surface both contrast with base in either polarity, so the splash now reads on light and dark themes alike. Adds imagemagick as a build-time input to the theme derivation. Like the background tint, this follows the theme as of the last system rebuild. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

# Plymouth boot splash — Nomarchy-branded (ported from the legacy

# iteration), background tinted from the same theme-state.json that
|
||
# drives the desktop (nomarchy.system.stateFile, wired automatically by

# lib.mkFlake). One caveat by design: theme switches are Home
|
||
# Manager-only and never touch the initrd, so the splash follows the

# theme as of the last SYSTEM rebuild (`sys-update`), not the last
|
