A developer of Iris showed that Horizon's shader pack code was written from
Iris's source. This removes it: the horizon-shaderpack crate, Java pack
loading and its render stages, Horizon's own WGSL packs and the example
packs, the Shader Packs screen and its option, the launcher's shader pack
browsing and installing, and the docs about them. Shader packs may come
back later as a clean-room rewrite.
The vanilla renderer and its post-processing (resolution scale, FXAA) are
unchanged. Options files that name a pack load and drop the key; the
launcher reads manifests that list a shader pack, and files in
`shaderpacks/` are never deleted.

- The desktop measured: Horizon v2026.10.22.13 against vanilla 26.3 at render
distance 12 and 32, 3 runs each, 1280x720, VSync off, in a headless sway on
the RTX 4080 (never on its screen). Replaces the "not yet measured" note.
- /benchmarks shows each players' group's hardware split (RAM, VRAM, drive,
system, GPU kind) and, once the telemetry server has some, a "Players'
hardware" table from /v1/aggregate's breakdowns. Hidden without data.
- The picker takes the memory too. Players' groups whose installs have neither
the picked RAM nor the GPU's VRAM class count as further away, and the result
says what they had and when a game's peak memory is a large share of the RAM.
- Each GPU in the spec table has its memory (0: shared).

- ThinkPad (i7-7500U, HD Graphics 620, Mesa): Horizon v2026.10.22.04 (two flights per scene) against vanilla
26.3 (two games) at render distance 12. Java loads chunks faster there and flies the mountain faster; the
page says so. Render distance 32 isn't published for it: neither game loaded the spawn in 5 minutes, and
Horizon kept only 900 to 1,400 columns resident when given 25.
- "Where Java is ahead" also lists scenes where vanilla's average beats Horizon's by more than 5%.

Three runs of each game at render distance 12 and 32 (tools/perf_bench.py, seed 1234, 1280x720, VSync off).
Horizon's average sits at the 144 Hz display (macOS presents in step with it even with VSync off): marked as
capped on the page.

Captured on the Mac mini with the game's offscreen capture (1280x720),
replacing the Horizon menu style's Video page.

Drop the Horizon menu style (options_horizon.rs, front.rs, the live title
backdrop and its post grade, the launcher's menu-style setting, CLI and MCP
tool). Every screen is vanilla's. Horizon's own settings hang off vanilla's
Options the way mods add theirs: Horizon Settings... and Mods... take the
Telemetry/Credits slots, and Horizon Settings opens Graphics, Advanced
Graphics, Shader Packs, Controller Settings, Extras and Mods, each a vanilla
options list with tooltips. Play with friends moves behind vanilla's Friends
buttons: the pause menu's opens Play with Friends (share, copy, stop), the
title screen's opens Join a Friend, and Direct Connection takes a full code.
Old files load as before: horizon.txt's menuStyle line and
horizon-graphics.txt's level line are ignored.

horizon-theme gains the Blocks palettes (light and dark, WCAG AA on every panel and on the stone),
Pixelify Sans (OFL) and Pixelarticons (MIT); tokens.css now carries the Blocks colours, the pixel
font and the block edges. The site sets headings, navigation and buttons in Pixelify Sans, turns
the index lists into stacks of panels with an outline, a bevel and a lip, puts a stone texture
behind the page and Horizon's pixel landscape (a dawn or a sunset) behind the hero, both drawn in
code by scripts/art.mjs. Light and dark still follow the system, with the toggle.

/docs has a left navigation and eleven pages written for players first, then
hosters, then contributors: what Horizon is, install, settings, multiplayer,
logs and bug reports, hosting (the launcher's Servers page and the command
line), modpacks, mods and data packs, performance, contributing and the FAQ.
/server redirects to /docs/hosting. The build checks every link between the
pages and every image.

Six scenes from one fixed-seed world (seed 8675309): a plains village among
savanna hills, sunset over it and the river, moonrise over its lit square, a
crimson forest with a zombified piglin, tropical fish over a warm-ocean coral
reef, and survival at dusk with a zombie and the full HUD. Plus Horizon's own
title, Singleplayer, Video options and pause screens.
Captured with horizon-ctl screenshot from the offscreen client (fullscreen
2560x1286 on the Mac mini, default graphics settings, GUI scale Auto), scenes
cropped to 16:9 and menus to 16:10 (left-aligned) and scaled to the old sizes
(1600x900, 1280x800). The scene sources are JPEGs in docs/media again, the
names scripts/assets.mjs already reads; the README's WebP copies are the
rebuilt website media. Alt texts and LEGAL.md follow the new pictures.
The launcher screenshots are unchanged: the Mac mini's session is locked, so
no window capture works.

What works on main today (install, game files, first run, server.toml, the commands, the web panel,
backups, services, Docker built by hand) and, plainly, what doesn't yet: offline mode only, no
published image, no secure chat or locator bar, the open PRs that are coming. The site renders the
guide into /server at build time, so it has one source. The CSP hashes now cover every page's inline
script, so the privacy page's theme script is allowed too.

/privacy says what the launcher may send when a player allows it (performance
summaries, crash and bug reports, benchmark uploads), why, on what basis,
where it is kept and for how long, and how to delete it. The footer links it.

The README banner is redrawn in the new design (docs/media/banner.html), and the launcher and
menu screenshots (README and website) are the restyled ones. The website's launcher section
gains a Launcher tab: its screenshots no longer show the old background, whose licence was
never confirmed.

The page now reads the design tokens generated from crates/horizon-theme (src/tokens.css, put
before style.css by build.mjs), and follows the system's light or dark appearance, with a
toggle that remembers the choice. The full-screen sunset hero is replaced by type: a headline,
one paragraph, the download, and an index list of what the page holds. Every section is a mono
label, a display heading and its content as numbered rows with one-pixel rules: the facts, the
fourteen subsystems, the launcher's features, the community links. Rows fade a soft plate in
under the pointer; content arrives with a short fade, rise and unblur. The footer ends on the
giant faint wordmark. The 404 page and the social preview (og.html) follow.
Instrument Serif, the hero images, the parallax, the statement fill and the magnetic buttons
are gone; the icons come from Horizon's new mark (xtask icons). Touch targets are 44 px high.

The mark is an H whose crossbar is the horizon: a violet line edge to edge, the stems above it
and their reflection below at a third, on whole units of a 16-unit grid so it stays sharp at
16 px. docs/media/brand holds the SVG masters (square icon, macOS tile, avatars, the mark for
light and dark backgrounds), the two alternatives that were shown with it, the GitHub social
preview and the Discord banner, and a README of what goes where and how to upload what only
Ludovic's accounts can.
`cargo run -p xtask -- icons` renders the masters (rsvg-convert) and packs, in plain Rust:
packaging/icons/horizon.ico and horizon.icns, Linux's hicolor icons 16–512 and the scalable
SVG, the game's run-time window icon, the avatars and the website's favicons.
packaging/linux has .desktop entries for the launcher and the game.
On Windows, build.rs embeds the .ico as icon resource 1 in horizon-client (and its tools) and
horizon-launcher (winresource, a Windows-only build dependency); gpui loads that resource as
the launcher's window icon. The game window sets the icon itself (X11, Windows) and names
itself `horizon` on Wayland so the desktop entry matches.

The launcher's palette, violet accent, Instrument Serif and Geist, without its sidebar
and settings rows: a full-viewport hero over Horizon's own sunset (slow drift,
parallax, grain), then sections for what it is (a statement that lights up as it
scrolls), a screenshot mosaic, the parity count and a grid of the 14 subsystems, the
launcher beside Horizon's own menus, the latest patch notes, the roadmap, community
and the footer. Reveals, staggered letters and magnetic buttons stop under
prefers-reduced-motion; a translucent top bar and a full-screen phone menu replace
the sidebar.
playhorizon.dev: canonical, og:url, absolute og/twitter images, sitemap.xml and its
robots.txt line, and a 301 from *.up.railway.app (Railway's healthcheck host is still
served).
The full-page screenshots are no longer committed (about 17 MB): `npm run shots`
writes them to the gitignored shots/. The unused blurred background is gone; LEGAL.md
lists the hero and the settings screenshot.

website/ holds Horizon's site: the horizon-theme tokens and bundled fonts, the
launcher's sidebar, rows, buttons and segmented control, over Horizon's own frozen
landscape. The parity table, harness count and roadmap are generated from the README
at build time; releases, patch notes, the roadmap and links.json are refreshed in the
browser from GitHub, with the build's copy as fallback. The download button picks the
newest launcher-v* asset for the visitor's OS.
Legal: the Minecraft disclaimer in the hero, footer and 404; no Minecraft logo or
wordmark; no game files; the launcher's background (licence unconfirmed) and the
screenshots showing it are left out; LEGAL.md lists every asset and its licence. No
cookies, analytics or third-party assets.
Railway: root directory website, Dockerfile (Node build, Caddy on $PORT with a strict
CSP). Checked with Playwright at 360-1920 px and 1250x700 (docs/widths/); Lighthouse
96/100/96/92 on mobile, 100/100/96/92 on desktop.
