/* Layout + base theme. Era tinting lives in eras.css.

   Palette note (WP-019 §4): every colour variable in this file and in eras.css was measured
   against both --bg and --panel with a headless Chromium at the six era themes in sequence, and
   --muted, --warn and --good were nudged darker (5–15%, hue kept) until every one of the six
   cleared WCAG AA 4.5:1 for body text. Nothing about the era drift moved.

   WP-020 UI pass (Jason's playtest feedback): the layout was rebuilt around information
   design rather than recolored — fixed grid columns for every number (tabular figures,
   right-aligned, nowrap everywhere a number lives), a real type scale (11/12/13/14/17),
   two-column card grids for buildings/techs so the center column stops being a monotonous
   stack of full-width bars, jobs and rosters constrained to readable measures, and press/
   hover states on everything clickable. Era palettes are untouched. */
