/* ── Divider sub-bab (W2.1, 2026-07-15; DIREVISI 2026-07-15 — lihat catatan bug) ──

   bergantung inline style yang cuma ada di ~43% file → divider tampil
   kiri-campur-tengah di ~794 deck. Fix terpusat di sini, NOL sentuhan file deck.

   ⚠️ BUG (ditemukan Boss via screenshot, sama hari): draf pertama pakai selector
   `:has()` untuk merata-tengahkan SELURUH section.vc ber-divider (termasuk h2/p.lead
   di ~78 deck varian title-only yang bukan class .divider-*). `:has()` TIDAK didukung
   Firefox <121 dan sejumlah browser lama — di sana rule itu senyap tak pernah berlaku,
   bug lama (kiri-campur-tengah) muncul lagi. Diperbaiki jadi 2 lapis TANPA :has() sama
   sekali:
   1) Class .divider-kicker/-title/-sub langsung dirata-tengah (kerja di SEMUA browser,
      classnya eksklusif dipakai divider — diverifikasi grep, aman disentuh langsung).
   2) Section pembungkusnya ditandai `.divider-slide` oleh JS (layouts/slides/deck.html,
      guard file — dijalankan sebelum Reveal.initialize, sama seperti fragmentHygiene)
      supaya elemen SIBLING non-class (h2/p.lead di deck varian title-only) ikut

   TIPOGRAFI KONSISTEN — safety net (audit 2026-07-25)
   2310/2394 deck menyalin template deck-design-system.css verbatim,
   yang punya KONTRADIKSI internal (.big 2.3rem vs 2.8rem, .divider-
   title 2.2rem vs 2.6rem, .lead 1em vs 1.05em) + 812 deck menambah
   inline h2=1.5em + 15.533 instance .big di-override inline ke nilai
   acak (4.363 tertekan ke 1rem = sama dgn body, hierarki lenyap).

   Blok ini MEMAKSA hierarki konsisten via !important supaya override
   inline non-!important di tiap deck. Skala: modular Major Third
   (ratio 1.25) di atas body 18px — kontras jelas tanpa rakus ruang,
   aman untuk deck padat (tabel/formula) agar tidak overflow 720px.

   !important di sini bisa DITUMPU lagi dgn inline !important di deck
   tertentu kalau memang perlu pengecualian (jarang). Setiap deck juga
   dibersihkan dari inline font-size heading/.big oleh script
   scripts/normalize_deck_typography.py — tapi safety net ini tetap
   dipertahankan sbg jaring pengaman utk deck varian & masa depan.

   - .big (biru accent) asli 2.5rem=40px didesain utk ANGKA kunci. TAPI 89%

     pendek ("2,5%", "Rp 400 M"), TIDAK rakus utk teks label 3-4 kata
     (wrap 2 baris rapi dgn line-height ketat). word-break supaya teks
     sangat panjang tidak overflow kotak.
   - .label (merah) naik 11→13px supaya terbaca (informasi sama pentingnya).

   ILUSTRASI SVG — safety net ukuran (audit 2026-07-25)
   1781/2394 deck punya inline <svg> (total 3765 instance). Masalah:
   - 1941 SVG pakai inline max-height:190-260px yang MEMAKSA ilustrasi
     pendek → hanya 30-40% area slide, ruang mati besar (keluhan Boss).
   - 280 SVG pakai fixed pixel (width=760 height=150) → tidak responsive.
   - 4827 <text> font-size ≤9 viewBox-unit → tidak terbaca saat render kecil.
   - 0 dari 3765 SVG dibungkus <figure> → rule existing (.reveal figure svg)
     TIDAK berlaku sama sekali.

   Strategi: fill LEBAR penuh, TINGGI mengikuti rasio aspek natural (height:
   auto). Karena viewBox SVG tetap, memperbesar render width OTOMATIS
   menaikkan readable font (font 11 viewBox-unit di SVG 800px render = 11px
   literal, tapi di SVG 1176px render = ~16px). Ini solve masalah font kecil
   TANPA harus edit tiap elemen <text>.

   TIDAK pakai :has() (lihat catatan bug Firefox <121 di baris 162-173) —
   pendekatan 2-lapis: selector langsung + !important utk bungkam inline.
