{# The shell every page is wrapped in. Rendered by sw.js, not by the build,
so editing this file changes every page without regenerating any of them.
Context: title, content (safe HTML fragment), mark (bookmark or null).
Bootstrap is the whole stylesheet. The fragments carry semantic USFM
classes and no Bootstrap ones, so the body text is styled by Reboot; the
chrome here is what uses the framework. #}
{% block title %}{{ title | safe }}{% endblock %}
{# Vendored rather than linked from a CDN: sw.js only caches same-origin
responses, so a CDN stylesheet would leave the app unstyled offline. #}
{# app.css comes second so its variable overrides win. It styles the
scripture; Bootstrap styles the chrome. #}
{# History entries are whole books, and htmx keeps its history cache in
localStorage -- a couple of them would blow the quota. Turned off, so every
back or forward is a cache miss, and refreshOnHistoryMiss decides what a
miss does.
False on purpose. True makes htmx call location.reload(true) -- a forced
reload, which is exactly the kind of navigation a browser takes past the
service worker, so it reaches server.py and comes back as boot.html: the
spinner flashes by and then reloads into the real page. False makes htmx
fetch the page over XHR instead, which the worker answers itself, from its
own cache when offline. No navigation, no boot page, nothing to flash.
That request carries HX-History-Restore-Request, and the worker answers it
with a whole composed document; htmx lifts the element marked
hx-history-elt out of the response and puts it back in the page. #}
{# The bundle carries Popper, which the navbar collapse and the modal do not
need -- but a dropdown or tooltip added later would, and this is one file
in the precache either way. Deferred scripts run in order, so `bootstrap`
is defined by the time app.js runs. #}
{# htmx is not deferred: hx-boost has to be in place before the first click. #}
{# Boosted links swap only the fragment, so the navbar, the modal and the
scripts above survive navigation and never reload.
No show: modifier, deliberately. htmx adds show:top itself for a boosted
link, but skips it when the href carries a fragment identifier and scrolls
to that anchor after the swap instead. Spelling show:top out here overrides
that decision for every link, which leaves a cross-reference like ISA#v61_6
sitting at the top of Isaiah. #}
{# col-xl-8 keeps a line of verse near a readable measure instead of running
the full width of a desktop window. #}
{# The swap target. hx-target on names this id, so every boosted
link lands here -- remove it and a click does nothing at all while a
full navigation still works. #}
{% block content %}{% endblock %}
{# Chrome, so it is written once here instead of built in JavaScript on every
page. app.js only fills in the reference and shows it. #}
