demo: "Try it" is its own page on the .com, in the landing page's style (#117)

Captain Bob, 2026-11-06: "I want the try it as it's very own page and
use the landing page we designed earlier ... as a baseline."

The landing page is the .com's Main.WebHome. The Try-it page follows
it: a floating box -- Your Machine, in place of Quick Facts -- a linked
title, == sections, {{info}} and {{warning}}. It goes at TryIt on the
.com (/bin/view/TryIt/), with the console embedded and links back to
the landing page and the source.

The page is on the .com now, so apache-demo.conf lets the .com frame
the console (frame-ancestors), and the demo's host is
try.starshipos-f18.com.

+== What You Are Looking At ==
+
+=== A Machine of Your Own ===
+
+Each visitor gets a separate machine, resumed at its prompt from one that booted, passed its
+power-on self-test (538 checks) and logged Zuse in -- so you do not wait for it to boot. When you
+leave, or after 30 minutes, it is stopped and discarded; the next visitor starts from the same
+clean state.
+
+=== The Build ===
+
+The demo always runs the most recent build that passed the project's **acceptance protocol**:
+booting on amd64, aarch64 and riscv64, the PC stick loaded the way a PC loads it, and the 32-bit
+build's tests -- the same checks every change must pass before it reaches the main line.
+
+=== Zuse ===
+
+**Zuse** is StarshipOS's superuser: whoever holds Zuse's identity drive. Here that drive is a
+demo Zuse minted for this page alone, attached to every session with its writes thrown away --
+not anyone's real identity.
+
+{{warning}}
+The demo runs in an emulator on a small server: it is slower than StarshipOS on real hardware,
+and only a few people can use it at once.
