/*
 * ATTAM frontend stylesheet (M4).
 *
 * Stili minimi non opinionati per le pagine pubbliche `single-course.php` e
 * `single-session.php`. Il tema attivo (o un override `theme/attam/...`) può
 * sovrascrivere o estendere queste regole. Nessuna dipendenza da utility
 * framework esterni (Bootstrap, Tailwind, ecc.).
 *
 * Approccio: spaziatura coerente, nessun colore hardcoded brand, nessuna
 * tipografia custom — il tema decide. Ci concentriamo su layout/struttura.
 *
 * BEM naming aderente alle classi dei template (`attam-course__*`,
 * `attam-session__*`, `attam-session-card__*`, `attam-trainer-card__*`,
 * `attam-course-card__*`, `attam-registration-form`).
