The web build has no font folder, so a text style whose TrueType file is
not a bundled Noto subset falls back to it. font_register takes the file
from the host page:
{"op":"font_register","file_name":"Brand-Regular.ttf","data_base64":"…"}
The faces join the font database, file_name resolves to the family of
the first face (case-insensitive, without directory, like installed
fonts), and open drawings lay their text out again (fallback glyph
cache cleared, text geometry invalidated per tab). The reply names the
family and the number of faces. Bytes without a face fail with
font_invalid. SysFonts::by_file becomes updatable for this.
Proposed in #1771.

The web control channel gains a save operation that serializes the
active drawing in the requested format and returns it as base64 in the
reply, clearing the dirty flag, the counterpart of opening from bytes.
A host page can also define window.openCadStudioSaveFile(name, bytes)
to receive every saved or exported file in place of a browser
download; while it is set no file picker opens.

Ported from 2c38de53 (#1717). Main already carries the hatch PDF draw
order fix (#1345), the numeric set_properties compare (#1348) and the
web open from bytes, so those parts stay out; what remains:
#1349 — window.ocsControl.ready/request promise wrapper with an
ocs-ready event (web/ocs-control.js, loaded by the web page), and the
startup donation prompt is suppressed once a control request is seen
(opt-in pre-boot via localStorage["opencadstudio.automation"] = "1").
docs/automation/web.md documents both. The control protocol stays at 1.
DATALINK CSV-to-table works on web (picker + bytes through the session
registry — was std::fs, silently dead); COLORSCHEME accepts System
(prefers-color-scheme on web, AppsUseLightTheme on Windows).
Decode accounting, made honest per the fix-of-fix review: into_rgba8
allocates the RGBA destination while the native buffer is alive for
every non-Rgba8 layout (L8 5, La8 6, Rgb8 7, L16 6, La16 8 B/px
peaks — the formula now says so), GIF bills the screen+frame
coexistence at 8 B/px, and TIFF drops the 3x multipliers both ways —
tiff 0.11 splits the given budget between frame and scratch (a total
ceiling), so the old double-billing refused honest 16-bit GeoTIFFs
~2.25x early while admitting hostile chunk transients at 3x.
(cherry picked from commit 2c38de53)
Describe the two JavaScript functions the web build exposes
(ocs_control_submit / ocs_control_take), how to poll them, the queue and reply
limits, opening a drawing from bytes with data_base64, and closing the startup
dialog before new. Everything is taken from src/app/control/mod.rs,
src/app/startup.rs and docs/automation/web_save_smoke.cjs.
