/* 248 Anthems — Royal Palm · "The Colonnade"
 * Brand System v2: bone page warmed to Boca daylight, graphite ink,
 * Barlow Condensed display, Inter text, IBM Plex Mono data.
 * Signal Lime is the system signal. ONE support colour: polished brass —
 * rules and numerals only. One whisper of coral, used exactly once (the
 * fine-print block where two third-party claims get corrected).
 * The page's own texture is a measured interval: faint vertical hairlines
 * at a fixed pitch, the colonnade abstracted into a grid. */
