/* Companion Field Guide — landing page
 *
 * THE BOOK'S IDENTITY, not a business unit's (DM, 2026-09-12). The page sells
 * a book; a reader who meets the cover and then lands here must be looking at
 * the same product. This supersedes the Battledress styling the page shipped
 * with earlier on 2026-09-12 — see 09_Web/README.md for the REC-550 reading.
 *
 * Palette sampled from the SHIPPED artefacts, not from the cover brief (which
 * proposed ink-navy/gold and was overtaken by what was actually built):
 *   Cover_Front_Commercial_6x9.svg, and Pictures/Korparc/linkedin/make.py
 *   whose own comment reads "Palette is the BOOK's identity, not Korparc's".
 *
 *   BONE #F2EEE5  ground         INK  #2A2420  type + dark surface
 *   CLAY #C96442  display accent  SKIN #E8C4A8  sub-ground
 *
 * ⚠ CLAY IS A DISPLAY COLOUR ONLY — 3.37:1 on bone, which clears AA for large
 * text and non-text but FAILS the 4.5:1 body threshold. Small text, links and
 * button labels take CLAY-DEEP #AE5132: same 15.1-degree hue, one step darker,
 * 4.51:1 on bone and 4.51:1 for bone-on-it. Do NOT tidy these into one value —
 * the split is what keeps the page at AA while still looking like the book.
 *
 * Type follows the book's own stack: Fraunces for display (self-hosted,
 * instanced to the cover's axes — opsz 144, SOFT 0, WONK 1) over the
 * interior's body stack 'Iowan Old Style', Palatino, Georgia. That stack is
 * system fonts by the book's own choice, so the body costs nothing to serve
 * and renders as the book does. No Google CDN (KP-STD-005).
