A new tab (globe, after Maps) shows one web page full-bleed in the content area —
no address bar, bookmarks or scrollbars — built for It Is Written but usable with
any page. It loads at startup and keeps running in the background.
Stage (browser-tab.js, browser-guest-preload.cjs):
- An Electron <webview> per Browser tab, in its own sandboxed process and persistent
session. The pages live in one persistent layer inside .tab-content: every tab
switch rebuilds .tab-content and moving a webview reloads it, so app.js now clears
around that layer (clearTabContentKeepingBrowser).
- Tapping a text field brings up the Prayer tab's keyboard (createPrayerKeyboard with
a sink) and types into the page with trusted input; Enter submits; the keyboard puts
itself away when the page moves focus on (e.g. after a search). The OS touch
keyboard is suppressed with inputmode="none" while a field is focused.
- Tapping a scripture reference opens it in a new Bible tab, in the translation
printed beside it when that one is switched on. References are found with the app's
own scanner: scripture-scan.js gains scanAll() (every match with its offsets),
translationAfter() and isTranslation(); scanText/parseSlide are unchanged.
- Input inside a webview never reaches the app, so the page reports activity (idle
splash) and five-finger touches (blank the screen) itself.
- main.cjs: webviewTag on; every webview is forced sandboxed, context-isolated, no Node,
http(s) only, with the guest preload. No new windows (opened in place), no permission
prompts, no downloads, no pinch-zoom, no alert/confirm/prompt boxes, and "Leave
site?" can never block Reload or Start page. The session reports plain Chrome.
- server.js CSP: frame-src allows http(s) (a webview is a frame to CSP); style-src and
font-src allow https (the follower's srcdoc copy inherits this policy).
Everywhere a tab kind is listed:
- app.js: create at startup and on Reset, icon, visibility defaults, + menu, fixed
mode, no ink layer, tool handling, OSC kind + information line (the page's search
term), phone remote scroll / tap / page buttons, OSC show / reload / home actions,
live setting changes, translation for tapped references.
- quick-dock, tool-wheel, presentation-tools: no drawing tools on the tab.
- Phone remote: tab label, one finger scrolls the page (taps still tap), hint text;
mirror-stream.js reports the page's scroll for the phone's local preview.
- Follower screen: the stage publishes a script-free copy of the page's DOM (only while
a follower is linked), its scroll and form fields; the follower shows it in
sandboxed, double-buffered frames; the relay keeps the page for late joiners.
- OSC: /bibleapp/browser, /bibleapp/browser/reload, /bibleapp/browser/home;
tab_kind/browser feedback. Admin and phone allow-lists updated.
- Settings: Tab Visibility, a Browser Tab section (start page, page size, scripture
taps, return to start page), Service Profiles carry its settings, OSC references.
- Admin console: show the tab, reload / start page, start page and page size.
- BROWSER_TAB.md documents it.
