 ### 7.1 Navigasi boosted (S9)
 - `<body hx-boost="true" hx-ext="preload,head-support" hx-target="#main" hx-select="#main" hx-swap="outerHTML show:none">`. Setiap halaman kerja membungkus **seluruh** isi (konten, sheet, `<template>`, skrip inline) dalam satu `<div class="container" id="main" data-nav="{{.Nav}}">`; header, tab bar, dan head tetap. `login.html` tidak memuat htmx; form logout `hx-boost="false"`.
 - Elemen htmx lain di dalam halaman (stats card, segmented) wajib `hx-target` sendiri dan `hx-select="unset"` agar tidak mewarisi `#main`.
-- Skrip halaman **idempoten**: dipanggil pada `DOMContentLoaded` dan `htmx:afterSettle`, dengan guard `data-init` (lihat `list.js`, `formatTimes` di `app.js`). Listener ke `document`/`window` dari skrip inline dilarang (menumpuk setiap swap): pasang ke `#main` atau elemen di dalamnya. Sumber daya hidup (WebSocket, xterm) mendaftar fungsi pembersih ke `window.dockifyCleanups`; `app.js` memanggilnya pada `htmx:beforeSwap` target `#main`.
+- Skrip halaman **idempoten**: dipanggil pada `DOMContentLoaded` dan `htmx:afterSettle`, dengan guard `data-init` (lihat `list.js`, `formatTimes` di `app.js`). Listener ke `document`/`window` dari skrip inline dilarang (menumpuk setiap swap): pasang ke `#main` atau elemen di dalamnya. Sumber daya hidup (WebSocket, xterm) mendaftar fungsi pembersih ke `window.dockifyCleanups`; `app.js` memanggilnya pada `htmx:beforeSwap` target `#main`. `charts.js` dan `console.js` dimuat `defer`: skrip inline yang memanggilnya saat parse dibungkus `dockifyReady(fn)` (app.js; menunggu DOMContentLoaded pada load penuh, langsung jalan setelah swap). Pembersih yang dipasang saat aksi user (Console) didaftarkan saat aksi itu, bukan sekali saat skrip dimuat.
 - Form dengan `onsubmit` yang bisa membatalkan harus memvalidasi lagi di `htmx:beforeRequest` (htmx tetap mengirim saat `onsubmit` mengembalikan false).
 - Respons tanpa `#main` (redirect ke login) jatuh ke load penuh; 4xx/5xx boosted tetap di-swap (halaman error).
 - Preload: atribut `preload="mousedown"` (touchstart otomatis) pada nav dan tautan baris; server menjawab permintaan `HX-Preloaded` dengan `Cache-Control: private, max-age=5`.
