/* ==========================================================================
 * PRIME NOD LAYER (2026-09-02) - lore.u.cash speaks prime.u.cash's grammar.
 * Plateless surfaces (transparent fills, 1px gold hairlines), square corners
 * (universal kill, prime.css:885 idiom), gold-outline action buttons (hover =
 * brighter ring, never a fill, prime.css:132-140), the terminal type duo
 * (Orbitron display / Space Grotesk reading, both self-hosted latin subsets),
 * AA-shifted gold per theme, and the painted six-gradient chamfer keyline as
 * the HUD signature (appshell.css:203-218 technique, lore-scoped tokens).
 * Base rules above stay untouched; this layer overrides by source order.
