/* ============================================================================
 * Nodepad design tokens - scoped app/workspace snapshot
 * ----------------------------------------------------------------------------
 * Design-system library member: nodepad.
 *
 * Source CSS: InventList app/assets/stylesheets/nodepad_tokens.css.
 * Typography docs: InventList docs/design/TOKENS.md, DESIGN_PRINCIPLES.md,
 * DESIGN_SYSTEM.md, and INTERACTION_PATTERNS.md.
 *
 * Copied into Kuickr on 2026-06-29 so agents can select Nodepad separately
 * from the broader inventlist.com design-system reference. This token sheet is
 * scoped: apply class="np-tokens" to the page root before referencing these
 * variables in generated HTML.
 *
 * Refreshed 2026-07-21 (spec 35.3) to matte surfaces + Inter, retiring the
 * editorial serif to the immutable 23a1cbe5 snapshot.
 *
 * REALIGNED 2026-08-16 (spec 35.4, founder instruction) to the identity the
 * founder supplied when this feature was built: Geist, Geist Mono, Instrument
 * Serif as the accent face, warm paper #faf9f7, near-black ink #0e0d0b, and
 * amber #e8901a as the accent.
 *
 * This CLOSES A SPLIT, it does not open one. The nodepad app-shell adapter
 * (app/assets/stylesheets/design_systems/nodepad_shell.css) has always mapped
 * Geist + #faf9f7 + #0e0d0b + #e8901a into the --kk-* roles, so the chrome was
 * already wearing this identity while this sheet said Inter and focus-green.
 * A page authored on `nodepad` therefore did not match the chrome around it.
 * They now agree.
 *
 * WHAT DID NOT CHANGE: every token NAME (nothing referencing --np-* breaks), the
 * operator brand roles (--np-memory / --np-focus / --np-distill are semantic
 * operator colours, not the accent), the kind chips, and the sticky fills.
 * The retired snapshots 23a1cbe5 and d15c7c07 stay addressable.
