/*
 * BlockForge — framework_core.css (block rules)
 *
 * All .bf-* block styling. Consumes the design tokens defined in
 * framework_theme.css. HARD DEPENDENCY: framework_theme.css MUST be loaded
 * BEFORE this file so the var() references resolve. Host load order is
 * framework_theme.css -> framework_core.css -> /Application/styles.css.
 *
 * Colour, spacing, radius, shadow, and the dark nav-sidebar palette are design
 * tokens (var(--bf-*)), not literals. A few genuinely bespoke layout one-offs
 * (e.g. odd paddings) and two semantic literals — the slate badge fill
 * (.bf-tree-badge--slate) and the accent hover tint (.bf-list-editor__add:hover) —
 * remain literal by design.
