/*
 * Typographic image scale — Anthony (Velvetyne)
 *
 *   s   → x-height (a, e, x)     bottom on baseline
 *   m   → ascender (d)             bottom on baseline
 *   l   → g / y body height         bottom on baseline (no descender in Anthony)
 *   xl  → cap height (A)           bottom on baseline
 *   xxl → parenthesis ( )          bottom on bracket descender
 *
 * Each tier exposes --img-{tier}-height and --img-{tier}-shift (em).
 * Shift lowers the box so its bottom matches a descender (brackets only).
