Once stylesheets were inlined, the editor's default CSS parser read
them through the browser CSSOM, where a shorthand that contains var()
(background: var(--surface-1), border: 1px solid var(--border)) comes
back as empty longhands. Every card, panel and border on an imported
page vanished, leaving text on a flat dark background. The official
PostCSS parser plugin keeps those declarations intact; vendored like
the rest, no CDN.
An Assistant drawer in Sirius Studio with two providers and no key, no
server and no spend. "This browser" runs an open model on the user's
GPU through WebGPU with WebLLM (vendored, Apache-2.0); weights download
once from the MLC mirror and stay in the browser cache. "Local
endpoint" talks to an OpenAI-compatible runtime on the user's machine
(Ollama, LM Studio), which unlocks larger models on a real GPU. Nothing
the user writes or builds leaves their device in either mode.
Three verbs: make a section, rewrite the selected text, restyle the
selection. The model returns HTML and CSS as data; Studio sanitises it
(no scripts, frames, handlers or imports) and inserts it through the
editor, with Undo. Model output is never executed.
The quantisation is chosen per GPU: q4f16 when the adapter exposes
shader-f16, q4f32 otherwise (Pascal-era cards lack it). Small models
often answer with bare HTML instead of JSON, so the parser accepts
both, prompts avoid literal placeholders one model echoed back, and an
out-of-memory or disposed runtime is reported as "pick a smaller
model" with the engine reset. Switching models starts a fresh worker.
Verified on an NVIDIA Pascal card: SmolLM2 360M rewrites text, Qwen2.5
Coder 0.5B builds a section; the 1.5B f32 build exceeded that card's
memory and now fails gracefully.
The editor panels were a muddy grey with pinkish text (4.7:1) because
the webpage preset injects its own demo palette after ours. That theme
is now switched off and the editor is themed through GrapesJS's CSS
variables: dark panels, near-white text (15:1 and better), acid accents,
readable inputs and toolbars.
Editing is closer to what people expect from Tilda: every box has drag
handles for width and height, the text toolbar gains size, colour,
highlight, alignment and heading controls, the font list has the site
families, and selecting anything opens the style panel. Nine ready-made
sections (hero, features, image+text, gallery, testimonial, pricing,
call to action, contact form, footer) drop in with their own styles.
Plugins vendored from npm (no CDN): forms, navbar, tabs, tooltip,
custom code, countdown, background styles, touch support; GrapesJS
itself is already current at 0.23.6. The basic blocks (columns, text,
image, video, map) had never loaded: the bundle registers itself as
gjs-blocks-basic, not grapesjs-blocks-basic. VERSIONS.txt records what
is vendored and how to update it.
Owners had no way to put a real page behind a name without running Sia
tooling themselves. Sirius Studio (studio.html, js/studio.js) embeds
GrapesJS (BSD-3, vendored under vendor/grapesjs so nothing loads from a
third party) with three starter templates; Publish exports one
self-contained index.html plus the editor project, uploads both to the
name's own folder bns/<name>/ on Sia, and sets the s3 record on chain if
the name does not point there yet. Drafts save to the same folder.
Gateway: /api/site/<name>[/<path>] — list, read-through, PUT and DELETE.
Every write carries a wallet signature over (name, path, body hash,
timestamp) that must recover to the current NFT owner, and writes are
confined to bns/<name>/ so no name can touch another name's bucket.
Dashboard menu is now Web-Builder, Domain names, My TLDs, Settings, Sign
out; Overview and Wallet folded into Domain names and Settings, Docs is a
link in Settings.
