* files: readable text previews in dark themes
A same-origin text document inherits the page's color-scheme, so dark
themes rendered the browser's default light text on the preview's
forced white background. Force a light color-scheme on the preview
iframe so text is always black on white.

* files: text previews follow the theme
Instead of pinning the preview iframe to a light scheme, follow the
theme: dark, night, and amber render the document light-on-dark against
the theme's panel color; light stays black-on-white.

* ui: a PDF asks before it lights up a night-adapted eye
Night and amber pass media through an SVG color matrix so nothing a user opens costs
them their dark adaptation. It reaches everything drawn in our own document -- images,
video, canvases, and same-origin iframes like the EPUB viewer.
It does not reach a PDF, and the miss is not subtle. Chrome draws PDFs in its own
out-of-process viewer, which the compositor paints outside the parent's filter: the
computed style on the iframe really does say `filter: url(#wrolpi-night-red)` and the
page still arrives in full color. Measured in night mode on a device, a PDF covered
55% of the doc page in non-red pixels -- a full-brightness photograph of a blue sky --
while the chrome around it was correctly red. The preview modal measured 39.8%.
Tinting from outside was tried and does not work. A red `mix-blend-mode: multiply`
overlay above the iframe cannot see the plugin's pixels, so it stops blending and paints
flat opaque red: zero non-red pixels by measurement, document entirely obliterated.
So the PDF is withheld and the reader chooses. Nothing renders until they do; hiding it
with CSS would still load and paint the viewer, which is the flash being avoided.
Gated on whether the theme is CURRENTLY filtering, not on its name. A reader who turns
night's filter off has said they do not want this, and amber with its filter on has the
same unreachable PDF and does. Only PDFs: text and the EPUB viewer are documents of our
own and tint correctly, so gating them would hide something for no reason.
The gallery paragraph claiming the matrix remaps PDFs is corrected -- it was the one
place we told users something this measurement disproves.

* review: the reveal that outlived its document, and a test that proved nothing
Five review comments, all correct.
The bug: MediaGate was not keyed in FilePreview. The effect that rebuilds a preview sets
the modal to null and then to the new content in one pass, so React 18 batches both and
reconciles instead of unmounting -- the fiber survives, and a reader who revealed PDF A
would get PDF B in full color with no prompt. Keyed by url, which is what Docs already
did with activePath.
The test named "re-gates when filtering is turned back on" never revealed anything first,
so it went from gated=false to gated=true with `revealed` already false. That path never
reaches the reset effect: the test passed with the effect deleted. It now clicks Show
first, and fails without the effect.
The hide control moved above the media. A preview fills `calc(100dvh - 18.75rem)`, a
height calibrated with no room for a trailing button row, so a control after it lands
below the fold of a full-screen modal -- leaving the reader who just lit up their eyes
scrolling to find the way back.
Docs' embed -- the surface measured at 55% non-red -- had no contract test where
FilePreview had one. It has one now, asserting the gate wraps the iframe, keys per
document, and reads mediaFilterEnabled rather than the theme's name.
Gallery copy said "night and amber withhold it"; amber's filter is off unless asked for.

Adds a split button to the STL and 3MF preview toolbars that opens the
model directly in a desktop slicer via its URL scheme
(scheme://open?file=<absolute media URL>). The slicer downloads the
file itself over the network.
Offers Orca Slicer, Bambu Studio, and Cura; the last-used slicer is
remembered in localStorage and becomes the split button's default,
since browsers cannot detect which protocol handlers are installed.
PrusaSlicer is deliberately omitted: it only downloads from domains
whitelisted by Prusa (printables.com, thingiverse.com, cults3d.com),
so it cannot fetch from a WROLPi.
