chall park. a pocket roller coaster tycoon opens at park.chall.net — isometric lawn, footpaths, six flat rides, stalls, and a piece-by-piece coaster builder whose auto-complete always finds its way home . guests wander in with needs and thoughts, the bank never runs dry (fun mode), and the park autosaves in the browser . one self-contained file: bright rct2 heart, ink-on-paper chrome.

the changelog grows up. this page rebuilt as a real changelog — releases grouped by day, each with a version, a tag (new · improved · fixed), its pacific ship time, and a plain description . unversioned pushes now appear as line items under the release they shipped on . restores v1.6.1, which the old page skipped.

the page ends quietly. removed the hairline rule above the version badge in the footer.

timeline, uninterrupted. removed the long horizontal rule after the timeline heading.

the paper stands alone. the display selector retires — grunge, crt, and the zen garden come off the public page . the default ink-on-paper look is the only look (the garden is replanted at admin.chall.net).

the zen garden. a sumi-e ink tree takes the third display slot — grows in over nine seconds, cycles through four seasons in seven minutes, sheds leaves that drift down the margins and pile at the foot of the page . reduced motion gets a still summer painting . retired in v1.22.0.

two transmissions. grunge paper and monochrome crt become switchable themes behind a display selector — persists locally, accepts ?theme=grunge|hacker.

back to the paper. the attack-center easter egg, dark mode, aurora wash, lamp, and theme toggle are all retired . no animation, no scroll tricks . white by default — just the ink and the timeline.

the screen becomes real. the site mapped onto the attack center's display with a true perspective fit (a trapezoid, not a rectangle), photo-registered edge feathering, and the room's optical softness . landing no longer off-center.

the attack center goes wordless. brand line and scroll hint removed from the easter egg — just the room.
