/* =============================================================================
 * csc-footer — three columns and a legal row
 *
 * Built to prototype round 11, section 13, at 1440 / 834 / 390:
 *
 *   ground   #0E1A2A full-bleed, band 1200
 *   columns  grid 1.6fr 1.2fr 1fr, gap 48, padding 36 top / 28 bottom
 *   legal    56 tall, separated by a 1px #2E3F55 rule
 *
 * ⚠ The dark ground is the accessibility fix. CSC's existing footer sets white
 * text on the brand blue #2D80C3, which measures 4.21:1 and fails AA for body
 * copy — a whole block of it, site-wide. The same text on --csc-ink reads
 * 17.4:1. Changing this ground without re-checking contrast undoes the point of
 * the section.
 *
 * Colour roles on this ground, all measured:
 *   headings   --csc-green-text     7.49:1   the one green, as TEXT
 *   links      --csc-on-dark        9.99:1
 *   phone      #FFFFFF             17.40:1
 *   legal      --csc-tag-on-dark    6.78:1   quietest, still clear of AA
 *
 * Padding, gaps and the grid are not Elementor controls — CLAUDE.md §2.10.
