board cap on one screen
## The wire is the effect stream, not a new protocol
`pardes --detach` leaves a core running with no terminal; `pardes --attach` is a frontend that owns
a terminal and a socket and nothing else. N frontends on one core all look at the same screen —
`screen -x`, not N sessions.
The codec (`src/detached/wire.zig`) carries exactly one `Event` or one `Host.VTable` call per
message. That is not a coincidence and it is why there is no third vocabulary to keep in step: the
core's IO seam was already a struct of function pointers with plain-data arguments, so a socket is
a legal implementation of it. `nested.zig`'s socket could not be reused — it carries a builtin
command line, and a command line cannot carry a frame.
ARCHITECTURE-NEUTRAL on purpose, not as decoration. The frontend on the far end may be
riscv32-freestanding on the ESP32-P4 while the core is x86_64 Linux, so every field is an explicit
little-endian fixed width and no message is a blit of a native struct. A protocol that only works
between two builds of the same compiler would have thrown away the one frontend that motivated it.
## The board comes in; its toolchain stays out
`src/p4.zig` becomes `src/esp32p4.zig`, and the pardes half of `../05-zig-p4` — the vaxis-over-
serial runner, the UART editor terminal, the keystroke rescue ring, the on-die test suite — moves
into `src/esp32p4/`. `build.zig.zon` gains `.zig_p4 = .{ .path = "../05-zig-p4" }`, so
`zig build -Dplatform=esp32p4 -Desp32p4-firmware` builds, flashes, monitors and self-tests the
board from this repo's `build.zig`.
The DIVISION is the point. What moved is what only pardes wants: the runner that drives a pardes
core over a serial line. What stayed is everything a second project would also want — the HAL, the
register/radio/oracle layers, the linker script, `_start`. `zig_p4` declares no dependencies of its
own and its `build()` early-returns when it is not the root package, so this costs the package
graph exactly zero packages and the editor's own builds nothing at all.
## limits.zig: nine forgettable places become one budget
Nine `platform == .esp32p4` capacity tests lived in nine files. They were never nine decisions —
they are ONE decision, how much memory this build may spend, taken nine times where no reader could
see the total. `src/limits.zig` puts the whole budget on one screen with every cap named against
what it is measured against, derived from two booleans.
The payoff is testability on a machine that is not the board: the caps are ordinary comptime values,
so a host build can be compiled against the board's numbers and the parking, eviction and clamping
paths a 240 KiB core takes get exercised by the normal test suite instead of only over a UART.
## A bare `zig build`
`zig build` with no arguments now builds the tty and GUI binaries and installs them into
`~/.local/bin`, and says so once on stdout with the flag that overrides it. The old default built
one binary into `zig-out` — a path nothing on a `PATH` ever looks at, which made "build it" and
"use it" two different commands for no reason.

theming, and mupdf -Djpx
Three commits off 38e9919 (macos-app@upstream) merged into main's ghostty bump.
No textual conflicts, and two things the merge needed:
- nested.zig asked libc for fstatat. Darwin has it; on linux std.c declares it
`void` (glibc hides it behind a versioned symbol std cannot name), so the tty
build stopped at 'type void not a function'. statNoFollow keeps fstatat on
darwin and asks statx on linux for the same three fields, which is what this
file did before the branch generalized it to both platforms.
- .DS_Store rode along with a797a1a. Deleted, and .gitignore now says so.
linux: snap 86/86, unit-test, image-harness and mupdf-check green. nested.zig
also type-checks for aarch64-macos.

The AppKit shell now draws what the core renders, follows the theme without a
relaunch, and builds into something you can hand to someone.
- Pixel attachments. Surface.images was dropped on the floor here, so a PDF
pane showed nothing at all: native_images is now set, pardes_image_s carries
the geometry the core already clipped, and PardesView keeps one CGImage per
(serial, page, revision) so scrolling costs a draw and not a decode. Image
panes get real pixels instead of the petscii fallback.
- Themes take hold live. pardes_tick never advanced the chrome animation, so
every tagline kept the previous theme's colours until the next launch and
the 16 ms re-pump spun for the rest of the session. pardes_theme_bg retires
the hand-agreed #121212 and drives the window background and the titlebar
appearance; a theme with no background of its own now gets a transparent
window over an NSVisualEffectView.
- The cell snaps to whole DEVICE pixels rather than whole points. Monaco
advances 8.4014pt at 14, so ceiling to 9 spaced every column 7.1% wider than
the face was drawn for.
- The dial is one notch per 10 degrees instead of 20, and a release keeps
turning in proportion to how hard it was thrown -- ramping up from zero at
the floor, so a slow twist coasts not a little but not at all.
- A file dropped on the grid is a click plus Look, so it opens beside the pane
it was dropped on. No drop concept was added to the core.
- The titlebar follows the focused pane: proxy icon, filename, and the dirty
dot. File.saved_revision is the watermark that last one needed.
- Config (SPC f c) prints the resolved startup config path.
- build.zig assembles, signs and packages the bundle itself; build-app.sh is
gone. -Dmacos-identity= takes a Developer ID, macos-dmg makes the image, and
the icon is Glenda.
