/* ---------- v05: blueprint theme (the book cover's drawing sheet), from the design panel ---------- */
/* Blueprint theme, final (design panel wf_3c3e2e30-0e2, 2026-10-07). Fonts load through the page head (Google Fonts link). */
/* =====================================================================================================================
   BLUEPRINT THEME, final. Appended after the base stylesheet; everything below overrides it.
   The site reads as one engineering sheet in the book cover's design system: cyanotype paper with the fine drafting grid
   and a slight mottle on every dark section, a double drawing border with zone markers framing each hero, dimension-line
   rules and overall dimension lines between sections, IBM Plex Mono drafting labels, amber hand notes used sparingly,
   the revision cloud around OG on the book page, and a title-block footer. Light reading sections are flat vellum.
   ===================================================================================================================== */
