/**
 * Mermaid.js — styling self-contained (tanpa bergantung CSS vars tema).
 * File ini hanya dimuat pada halaman yang memuat diagram (lihat
 * `layouts/_default/baseof.html`). Di-scope ke `pre.mermaid` saja
 * supaya aman disisipkan ke layout manapun.
 *
 * Sinkron dengan `bestpractice.unisbadri.com/_custom.scss` (bagian
 * Mermaid) — kalau salah satu di-update, idealnya yang lain ikut.
 *
 * Kontrak kelas:
 *  - `pre.mermaid`                     : kontainer diagram (sebelum render berisi teks sumber).
 *  - `pre.mermaid[data-processed]`     : sudah dirender jadi SVG.
 *  - `pre.mermaid[data-mm-enhanced]`   : toolbar & pan/zoom sudah dipasang.
 *  - `pre.mermaid.is-dragging`         : sedang di-drag (pan).
 *  - `pre.mermaid > .mermaid-toolbar`  : toolbar control (top-right).
 *  - `pre.mermaid .mermaid-btn`        : tombol individual.
 *  - `pre.mermaid .mermaid-zoom`       : label persentase zoom.
 *  - `pre.mermaid .mermaid-sep`        : separator vertikal di toolbar.
 *  - `[data-tooltip]`                  : tooltip teks custom (pengganti `title`).
