Fimeg 8f42fc953d publish: the public projection begins here
This is a projection, not a development branch. The tree above was constructed
from the internal source named below under a manifest that decides which paths
may leave, then scanned as a whole tree rather than as a series of patches, and
only then published.

Public history starts here because the history before it was not admissible,
and neither was the tree. What used to stand in this repository included a
rescue copy of another machine, a directory of phone handoffs, deployment
wired to one house, and a submodule pointing at a forge no stranger can reach.
None of that was ever the product. It stays in the private forge, which is
allowed to hold the whole working organism, and this is what was deliberately
sent out instead.

Three mechanisms produced this tree, in decreasing order of trust. A top-level
path the manifest does not name never arrives at all, which is the one that
catches directories nobody has thought of yet. Named internal files inside
admitted roots are dropped. A short, reviewed table replaces deployment
defaults that a public build must not carry -- an endpoint aimed at one LAN, a
VPN profile belonging to one phone, packaging built from one checkout path.

Everything after this commit is an ordinary publication with the same three
trailers, so a force push stops being routine and starts meaning that
something deliberate happened. The trailers bind the projection to its source
without pretending the public SHA is the private one: same lineage, different
tree, and the record says so.

// DockStack — macOS-Dock "Fan" mode for a stack of apps (2026-07-11).
//
// Collapsed: a single stacked-cards icon (the topmost member) with a count
// dot, like a pinned app. Tap or long-press to expand.
//
// Expanded: member icons arc UP off the dock along a polar curve. Angle
// sweeps ~90deg (straight up) to ~55deg across N members; radius grows per
// item so they don't overlap. Slide a thumb up the arc — the icon under the
// finger scales/highlights; release launches it. Release off the arc (or a
// plain tap on empty space) collapses without launching.
//
// The arc lives in its own PopupWindow (like previewPopup in DockApps.qml)
// so it can draw ABOVE the dock's own bounds. Icons animate x/y from the
// collapsed origin out to their arc slots, driven by one `expanded` bool.
