/**
 * public.css
 * Token desain & reset dasar yang DIPAKAI BARENG oleh semua halaman publik standalone
 * (landing, kebijakan privasi, referral, katalog online) -- landing/index.php,
 * landing/kebijakan_privasi.php, landing/referral.php, landing/toko.php,
 * landing/panduan.php, landing/katalog-info.php, katalog/index.php, katalog/pesanan.php.
 * Halaman-halaman ini TIDAK memakai Tailwind CDN/custom.css (sistem desain beda total
 * dari app yang sudah login -- lihat base.css/components.css/layout.css di folder yang
 * sama, itu semua Tailwind-utility-replacement).
 *
 * SEKARANG JUGA memuat NAVBAR + SIDEBAR MOBILE + TOMBOL CTA + FOOTER BERSAMA yang
 * DIPAKAI SAMA PERSIS oleh semua halaman publik landing/* (KECUALI katalog/index.php &
 * katalog/pesanan.php -- itu ETALASE TOKO pembeli, bukan halaman marketing, punya
 * topbar/tanpa-footer sendiri yg TIDAK ikut sistem ini) -- lihat partial
 * `landing/_navbar.php`, `landing/_cta_banner.php`, `landing/_footer.php` (markup HTML-
 * nya, di-require tiap halaman landing/* supaya BENAR-BENAR 1 sumber, bukan disalin-tempel
 * per file lagi spt sebelumnya). Sebelumnya tiap halaman baru (toko.php/panduan.php/
 * katalog-info.php) bikin topbar/footer/tombol CTA sendiri2 -- makin lama makin
 * bercabang & TIDAK responsive (menu nav di index.php sampai 7 item, di layar HP cuma
 * di-`display:none` tanpa pengganti apapun, hilang total) -- makanya ditarik jadi 1
 * sistem di sini SEKALIGUS ditambah sidebar collapse utk HP (lihat blok NAV di bawah).
 *
 * Token/aturan yang MEMANG beda per halaman (mis. `--danger`/`--success` cuma di
 * katalog, `body{background/line-height}` beda2, `a{}` beda gaya per halaman) TETAP di
 * <style> inline masing-masing file sbg tambahan/override di ATAS file ini.
