fix: land the missing desktop changesets and repair dark-mode desktop UI#92elkaix wants to merge 7 commits into
Conversation
The Host port fix and the dedicated desktop update channel both merged without a changeset, so neither is versioned or recorded in the desktop changelog.
Lead with a dark hero that presents the desktop app and an app-window preview, make the nav react to scroll, expand the cursor-aware particle field, and drop the CSS bubble decorations and the separate desktop showcase section.

The macOS sidebar renders on a translucent light surface, but the dark palette picked secondary text colours for an opaque dark background, so the workspace header, session timestamps, and the settings row disappeared. Raise the three faded tokens in both dark blocks, keeping their hierarchy.
The dialog shell had a fixed height with no overflow clipping, and its body only scrolled below 640px. On desktop the body overflowed, pushing the actions row and footer outside the shell, so the bottom border drew across the Cancel button.

…s pill The dropdown opened upward with no height limit, so a long provider model list ran past the top of the window and the models above the fold could not be reached. Measure the pill on open and cap the menu, letting it scroll.
The macOS window used vibrancy over a transparent background, so the dark palette rendered on a translucent light surface its secondary colours were never designed for. Drop vibrancy and transparency and paint the palette's own background colour, keeping the per-platform window chrome.

Related Issue
No issue. The problem is explained below.
Problem
Two things, both discovered while checking whether the recent desktop fixes had actually shipped.
1. Two desktop fixes merged with no changeset.
@pymodel/pythinker-desktopis versioned by changesets — it is not in theignorelist in.changeset/config.json, it has its ownCHANGELOG.md, and the release bot has bumped it to0.1.2. But the Host-port fix and the dedicated-update-channel change both merged without achangeset, so neither is versioned and neither appears in the desktop changelog. The latter PR's
checklist stated the package is "private and changeset-ignored", which is not the case.
The practical effect:
PyModel/pythinker-desktop-releases, which is now the desktop updatechannel, holds no releases at all, and the newest desktop build published from this repository is
the
v0.1.0pre-release. Neither fix reaches a user through any published build or release note.2. The site hero did not lead with the desktop app.
The desktop app was presented in a mid-page showcase section while the hero led with the CLI, so
the primary download was below the fold.
What changed
Changesets (patch,
@pymodel/pythinker-desktop→0.1.3)when a packaged build carries no update feed.
No CLI changeset: none of the recent desktop, site, or server changes enter the
@pymodel/pythinker-codebundle, so a CLI entry would be inaccurate.apps/siteis not versionedby changesets and deploys on merge.
Site
desktop showcase section is removed.
Dark-mode legibility on the desktop sidebar
The macOS sidebar renders on a translucent light surface (
vibrancy: 'sidebar'), but the darkpalette picked its secondary text colours for an opaque dark background. The workspace header,
every session timestamp, and the settings row were effectively invisible; text using
--inkwasunaffected.
--dim,--muted, and--faintare raised in both dark blocks — the explicit-darkselector and the system-dark media query — keeping their existing hierarchy. Changing only one
block would have left half the users broken.
New-session dialog containment
The dialog shell had a fixed height, a border radius, and no
overflow: hidden, while its bodydeclared
overflow-y: autoonly below 640px. At desktop width with several recent directories thebody overflowed, pushing the actions row and footer outside the shell, so the shell's bottom border
drew a line across the Cancel button. The body now scrolls at every width (
min-height: 0included,since a flex child will not otherwise shrink) and the shell clips to its radius. The three sibling
dialogs already did this; this one was the outlier.
Desktop packaging test
The test extracted a
<section id="desktop">block from the site source. The hero rework moved thatanchor onto the hero header, so the match returned null. The assertion now binds the Windows icon to
the desktop download entry, so it cannot pass on the unrelated CLI install rows that use the same
icon.
Blocker for the next desktop release
This PR only versions the fixes. Building them still needs a
desktop-v*tag or a manual workflowrun, and the release workflow reads two repository secrets that do not exist yet:
DESKTOP_RELEASES_APP_IDDESKTOP_RELEASES_APP_PRIVATE_KEYThere is deliberately no
