What is Spectra?
Spectra Blocks Pro 1.0.7 fixes headers on block themes as the fidelity work continues.
Spectra Blocks spent the autumn on fidelity: matching editor previews to live sites, fixing classic-theme spacing and Site Editor alignment, and letting its content count toward Yoast and Rank Math. 1.0.14 improved front-end loading and Slider accessibility, 1.0.15 added custom HTML attributes, and Pro 1.0.7 fixes per-page headers on Full Site Editor themes along with Loop Builder, Countdown and Modal rendering.
What is Zeroheight?
Design system documentation making itself the constraint on AI-generated UI
Three releases in February, each recorded twice. An AI Assistant embedded in SSO-protected styleguides lets viewers chat with the guidelines to find tokens and guidance. The same Assistant became available inside Slack and Microsoft Teams via mention. And a Figma-verified connector for Figma Make brings documented design system guidance into AI-powered prototyping.
Spectra vs Zeroheight: editorial side-by-side
Spectra
5.0DESIGN
Spectra Blocks Pro 1.0.7 fixes headers on block themes as the fidelity work continues.
◆ Current state
Spectra Blocks spent the autumn on fidelity: matching editor previews to live sites, fixing classic-theme spacing and Site Editor alignment, and letting its content count toward Yoast and Rank Math. 1.0.14 improved front-end loading and Slider accessibility, 1.0.15 added custom HTML attributes, and Pro 1.0.7 fixes per-page headers on Full Site Editor themes along with Loop Builder, Countdown and Modal rendering.
◆ Where it's heading
After the AI page import push in September, releases have been about trust in the output: render it correctly, make it count for SEO, now make it fast and accessible. The Pro add-on follows the same cadence with design-token and dynamic-data fixes.
◆ Prediction
Expect accessibility passes on other interactive blocks such as tabs or accordions, following the Slider, alongside further Pro fix rounds.

Design system documentation making itself the constraint on AI-generated UI
◆ Current state
Three releases in February, each recorded twice. An AI Assistant embedded in SSO-protected styleguides lets viewers chat with the guidelines to find tokens and guidance. The same Assistant became available inside Slack and Microsoft Teams via mention. And a Figma-verified connector for Figma Make brings documented design system guidance into AI-powered prototyping.
◆ Where it's heading
zeroheight's problem has always been that documentation nobody opens does not govern anything. All three releases attack that from different sides: bring the docs to where people already are (Slack, Teams), let them be asked instead of read (Assistant), and inject them into the tool that generates UI (Figma Make). The last is the most consequential, because it changes documentation from a reference into an input.
◆ Prediction
Expect connectors for further AI generation surfaces beyond Figma Make, since the Figma Make integration establishes the pattern of design system guidance as generation context rather than as a page someone consults.
