Keystone's design taxonomy — the 21 macrostructure names, the 50 component
archetype codes (H1–H9, S1–S5, F1–F6, C1–C4, T1–T4, Ft1–Ft8, N1–N13), the 58
anti-slop gate concepts, the 4 genres (editorial / modern-minimal /
atmospheric / playful), and the 7-step build-flow skeleton — is derived from
Hallmark (https://github.com/Nutlope/hallmark), authored by Hasan El Hajji
(@Nutlope) and contributors, released under the MIT License.

Per the curated-rewrite policy in Keystone's design spec:
  - Macrostructure NAMES and archetype CODES are reused (stable IDs / factual
    labels).
  - All prose is rewritten in Keystone's own voice.
  - The executable gate-checker annotations, the enforcement engine, the
    Playwright render extension, the 8 deep theme specifications, and the
    engine-verified Step 7 loop are Keystone's original contribution.

Hallmark's MIT license is preserved in the upstream repository
(https://github.com/Nutlope/hallmark/blob/main/LICENSE) and acknowledged here
with thanks. See the README section "How Keystone relates to Hallmark" for the
