// Preload for the page-dialog overlay (js-dialog.html): the Theseus-drawn
// replacement for a page's alert / confirm / prompt. Main pushes one request
// at a time via `jsdialog-show`; the page answers with `jsdialog-answer`.
const { contextBridge, ipcRenderer } = require("electron");
contextBridge.exposeInMainWorld("jsdialog", {
  onShow: (cb) => ipcRenderer.on("jsdialog-show", (_e, req) => cb(req)),
  // value: a string for prompt(); { response, checkboxChecked } for one of Theseus's own prompts.
  answer: (reqId, ok, value) => ipcRenderer.invoke("jsdialog-answer", reqId, !!ok, value == null ? null : (typeof value === "object" ? value : String(value))),
});
feat(theseus): page dialogs drawn by Theseus instead of Chromium's stock boxes alert / confirm / prompt from a page came up as bare OS message boxes titled "theseus-navigator" (the package name), with no hint of who was asking and nothing of the browser's styling — the PDF Editor's "Delete signature?" was the reported case. The session preload replaces the page's three functions with wrappers that hand the call to the isolated world through a DOM event, which asks main synchronously and writes the answer back; pages see Chrome's return values (confirm → boolean, prompt → string or null) and no new global. Main answers from a sheet hanging under the toolbar, in the same surface as add-on approvals, that names who is asking: the site's host, the add-on's name for an add-on page or panel (identified by its path under the profile's extensions directory), or Theseus for its own pages. The sheet belongs to the tab that asked — hidden while another tab is in front, back when its tab returns — and a closing tab or window answers "cancel" so no renderer stays blocked. Windows without the chrome (installed apps, plain windows) get a native box with a proper title, and app.name now reads "Theseus Navigator" for whatever else still shows one. 2026-09-27 17:53:21 +02:00			`// Preload for the page-dialog overlay (js-dialog.html): the Theseus-drawn`

feat(theseus): Theseus's own prompts use the dialog sheet too Install-this-app, remove-app, the extension install flow (install, already installed, installed, not found, failed) and the add-on restart question were still bare OS message boxes titled "theseus-navigator" after page dialogs moved to the sheet. askSheet() is a drop-in for dialog.showMessageBox with the same options and result: title as the headline, detail under it, the caller's buttons with the default first, an optional checkbox, and the app's or extension's icon when there is one. Tone follows the box type (error, warning) or the wording. The native box stays as the fallback when the browser window is not there, and for the two synchronous cases (beforeunload, app windows). 2026-09-27 20:13:06 +02:00			`// value: a string for prompt(); { response, checkboxChecked } for one of Theseus's own prompts.`
