/* =====================================================================================================================
   MEBLE DLA DEWELOPERA — arkusz wspolny (2026-11-12). Koncept WLASNY platformy: „PLAN ARCHITEKTA”.
   - tlo len / piasek (nie biel i czern sklepu LIVINGHOME), cieply grafit #2B2724 jak u producenta, MOSIADZ zamiast zlota (#A27B45),
   - kroje: Instrument Serif (naglowki; producent ma Marcellus), Hanken Grotesk (tekst), JetBrains Mono (wymiary, metryki, podpisy rzutow),
   - siatka kreslarska, cienkie linie wymiarowe, numeracja arkuszy (A-01…), rzuty SVG w skali — „deweloperski” jezyk zamiast lifestyle,
   - komponenty: karta techniczna produktu (.kt), metryki inwestycji (.metr), os czasu etapow (.os), arkusz wyceny (.ark).
   Mobile (standard platform): ponizej 768 px zadnych tabel przewijanych w bok — wiersze jako karty, strefy dotyku min. 44 px, pola 16 px.
