/* fpmi_callouty-theorem: FPMI house style for theorem-like environments,
 * ported from cu-callouty-theorem (same structural technique: thin uniform
 * border + a full-width tinted header bar built from Quarto's own native
 * inline title span), recolored to the accent palette already used for
 * these environments in fpmi-format/theme.scss's old bare-.theorem rules.
 *
 * All types run with `override-title: false` (see _quarto.yml), so Quarto
 * renders its own native title INLINE at the start of the body -- e.g.
 * <span class="theorem-title"><strong>Теорема 1</strong></span> -- already
 * carrying the crossref number for free. We don't rebuild it, we just turn
 * that inline span into a full-width header bar with CSS.
