/* Zwroty — panel biura (biuro.css). Dokłada się do styles.css i używa jego zmiennych
 * (--bg, --surface, --text, --muted, --primary, --ok, --warn, --error, --border, --radius oraz --ink, --line, --accent…).
 *
 * Kierunek: surowe narzędzie robocze / księgowe bez „AI slop”.
 * - Zwarta hierarchia promieni zaokrągleń: panele 6 px, kontrolki/przyciski 4 px, znaczniki 3 px.
 * - Nawigacja boczna na komputerze osadzona na powierzchni roboczej (var(--surface)) zamiast czarnej,
 *   oderwanej wyspy na jasnym tle; na telefonie zwarty pasek zakładek mieszczący wszystkie 4 sekcje na 390 px.
 * - Gęste, czytelne tabele z jednowierszowymi akcjami na komputerze i wyrównaniem cyfr tabelarycznych.
 * - Brak zagnieżdżonych podwójnych ramek (tabela w panelu oraz wiersze pozycji w formularzu bez „karty w karcie”).
 * - Zwarty panel filtrów na telefonie, dzięki któremu pierwsze wiersze listy dostaw zaczynają się w górnej połowie ekranu.
