/* ============================================================================
 * Isle of Trains: All Aboard - Campaign Logbook
 *
 * A printed reference sheet, not a dashboard. Everything sits on one full-bleed
 * island scene - bright sky, sun, clouds, rolling hills, the line running across
 * them - and the chapters are dense bordered cards printed on top of it, each
 * carrying the same strong flat-colour blocks the campaign sheet in the box
 * uses: gold Objective, green Special Rules, heavy dark borders on everything.
 *
 * Deliberately NOT: translucent panels on a dark background, generous padding,
 * hairline borders, muted tints. The source material is a boldly printed sheet
 * of card, so the borders are thick, the fills are solid, and the gaps are small.
 *
 * Palette. The scene sits two steps down in lightness from a midday sky, so the
 * cream cards printed on it stay the brightest thing on the sheet:
 *   sky            #2275a5 -> #49abd8
 *   sun            #eec72f
 *   clouds         #dbe8ef
 *   hills          #6eb441 / #4f8a3a
 *   grass strip    #4f8a3a / #5a9c3f
 *   embankment     #c39056
 *   ink (all rules)#23372c
 *   paper          #fbf3de   dull paper #ece0c2
 *   gold block     #f3c33f
 *   green block    #7ac86a
 *   signal red     #d94f3d
 *
 * All selectors are scoped under .iot-tracker so the global
 * reset-typography.css cannot override fonts on bare element selectors
 * (known overlay gotcha).
