/**
 * FCT Shared Premium Foundation (WAVE F0)
 * ---------------------------------------------------------------------------
 * OPT-IN ONLY. Nothing applies unless an ancestor has class `.fct-ui`.
 *
 * Canonical sources consolidated from:
 *   - `.pap-surface` / `.pap-btn*` (fct_ui_pages.css)
 *   - Config CT compact form grammar (`.cfg-turma-fct-form .form-control-sm`)
 *   - `.fct-dc-hub` `--dc-*` tokens (paineis_fct.css)
 *
 * HARD RULE: do NOT restyle global Bootstrap:
 *   .form-control / .form-select / .form-check / .btn
 *
 * Actions: prefer existing `.pap-btn` / `.pap-btn--primary|secondary|ghost|danger|sm`.
 * Typography levels (max 4): title → section → row-primary → meta.
 * Spacing: field < group < section via --fct-ui-space-*.
