/* Peptide Compliance Registration — Institutional Application Form */
/*
 * These styles are intentionally structural. Typography (font family, base
 * color) is inherited from the active theme so the form reads as native page
 * content. Surfaces and borders are derived from the inherited text color via
 * color-mix(), so the form adapts to both light and dark themes. Brand accents
 * come from --pcr-primary / --pcr-accent, which are injected inline and default
 * to the theme's own color presets (see PCR_Settings::color_css_value).
 *
 * Every color-mix()-based value is paired with a solid fallback (either a
 * preceding literal declaration or a var() fallback) so browsers without
 * color-mix() support still render sane borders, surfaces and muted text.
