Problem

npx @frontlit/preview@alpha frontlit crashes on a fresh install:

SyntaxError: The requested module '@tiptap/core' does not provide an export named 'isValidCSSStyleValue'
  at …/@frontlit/text-editor/node_modules/@tiptap/extension-table/dist/index.js

Cause

@frontlit/text-editor pinned three tiptap packages exactly (@tiptap/extension-code, @tiptap/extension-code-block and @tiptap/extensions at 3.31.3, added in 08c80fc) and gave the rest caret ranges (^3.0.0, ^3.10.7, …).

In the monorepo, bun.lock holds everything at 3.31.3, so nothing broke here. A fresh npm install, which is what npx does, behaves differently:

• The caret ranges resolve to the latest tiptap (3.34.0), so @tiptap/extension-table 3.34.0 needs @tiptap/core ^3.34.0.
• The pinned 3.31.3 packages need @tiptap/core 3.31.3, so npm nests a second core 3.31.3 under @frontlit/text-editor/node_modules.
• extension-table sits in that same nested folder, so Node resolves it to core 3.31.3, which doesn't have isValidCSSStyleValue.

Fix

• One range for all tiptap dependencies: every @tiptap/* dependency of @frontlit/text-editor is now ^3.31.3, so npm resolves a single tiptap version. Tiptap publishes all its packages together. bun.lock still resolves 3.31.3; only the specifiers changed.
• Theme border colour in the preview: @frontlit/preview now gives borders the theme's border colour, as apps/sites/app/globals.css does (* { @apply border-border }). Without it, Tailwind 4 defaults borders to currentColor, so preview cards, dividers and the header border rendered in the text colour.

Changesets: @frontlit/text-editor patch and @frontlit/preview patch. @frontlit/page-builder pins text-editor exactly, so the changesets bump it too, and the preview picks up the fix once all three are released.

Verified

• Fresh npm install: published @frontlit/preview@0.1.0-alpha.6, with this text-editor swapped in through overrides, installs a single @tiptap/core (3.34.0) instead of two. The preview starts and renders a 21-page site (CourseLit's frontlit/ folder).
• Borders: with the CSS change, card borders compute to the theme's --border colour instead of the foreground colour. Utility classes such as ring-primary still win.
• Tests: text-editor passes 110 of 110 and preview passes 2 of 2.
