The inspector's width bounds were 75-100 average character widths, which on
macOS (8 px) came to 600 px for content that needs 397. They are now
measured: at least the panel's minimum size hint plus the scroll bar, at
most a third more. CollapsibleSection reports its folded content's width
in minimumSizeHint, so the panel keeps its width when a section opens. On a
font change the measurement waits a turn, until the children have the new
font.
When shrinking the window would leave the image narrower than the
inspector, the inspector folds away, with the magnifier if it shares the
inspector's column; they come back once the image would still be at least
as wide as the inspector (plus 40 px of hysteresis). Only a shrink folds, a
dock shown by anyone else is no longer the window's to restore, and folded
docks are saved as open. Measured on a 1920 px screen: folds at 1140 px,
returns at 1260 px; at 960 px the image gets 620 px instead of ~145.
Dark theme: disabled text is set explicitly (#858AAE, ~4.8:1 on the panels)
instead of the derived colour, which was nearly the panel colour and made
greyed-out fields look empty. The splash text is black in either theme:
its message is rich text, which takes the palette's text colour rather
than showMessage's.

The right end of the display toolbar now carries three "A" buttons for the
100/125/150 % font sizes and a light/dark switch (a sun with a half-filled
disc), so both settings are visible without opening the View menu. The size
buttons and View > Font size stay in sync through JFJochViewerMenu's new
SetFontZoom / fontZoomChanged; the View > Theme tick follows ThemeNotifier,
so it moves when the toolbar switches the theme.
With Qt 6.8+ an explicit Light or Dark choice is also requested from the OS
(QStyleHints::setColorScheme), so the title bar macOS and Windows draw
matches the window, as apps with their own theme switch do. Follow system
withdraws the request first, since Qt otherwise reports the requested scheme
instead of the desktop's.
The image counter reads "1 / 1800" instead of "1/1800".

View > Theme offers Follow system / Light / Dark, stored in the settings.
Follow system uses the desktop's colour scheme where Qt reports it (6.5+)
and is light otherwise. The dark theme is a deep indigo (#1A1D3A panels,
#12142B entry fields and charts).
The palettes live in the new ViewerTheme module. A switch applies at once:
the application stylesheet is set again after the palette so every widget
is re-polished (with a stylesheet active, polished widgets otherwise keep
their old palette); widgets that bake colours into stylesheets use
SetThemedStyleSheet, which re-applies them on ThemeNotifier::changed;
toolbar icons draw their glyph at paint time through an icon engine, so the
ink follows the theme (and stays sharp at any size); charts re-theme and
rebuild. Hard-coded white backgrounds on entry fields and tables are
removed in favour of the palette's base colour.
The idle detector-status badge in the status bar is now transparent instead
of an empty default-styled progress bar.
