Reflect answers currently lose paragraph spacing, heading hierarchy, and list markers. The UI uses prose classes, but Tailwind v4 does not automatically load the typography plugin registered in the legacy JavaScript config. Long answers consequently read as a dense block of text.

This registers the existing typography dependency in CSS, following Tailwind's v4 instructions. Reflect answers use 16px body text with 28px line spacing, clear heading sizes, and text blocks capped at 70ch. Tables and code can use the card width; wide tables scroll within the answer without compressing words into narrow columns. Table scroll positions survive edits to the Reflect controls. The existing Inter and JetBrains Mono fonts remain.

The plugin replaces the manual Markdown table overrides and restores styling for other existing prose consumers, including directives and Reflect observation details. CompactMarkdown opts out with not-prose to preserve its own compact styles.

Validation

The current branch is rebased onto main at a921929a0. Local tests, lint, and build checks cover d3c1438743624314043f457a2af877c83d087c7f; Git range-diff confirms both PR patches are unchanged by the rebase.

• CI on this head completed with 78 successful checks and 23 skipped; no failures.
• Compiled-CSS regression test fails before the plugin registration and passes afterward.
• Control-plane tests: 40 files, 285 tests passed (TZ=UTC, two workers).
• Repository lint/type checks and control-plane production build passed. The Meta Muse integration also passed all 17 tests locally after the rebase.
• Initial Chromium checks covered light/dark at 1440, 768, and 390px, 200% text scaling, nested lists, and compact-renderer sizing. Independent review then identified table compression and scroll resets that those checks missed.
• Follow-up regressions fail at the initial PR head and pass with the fixes: a rendered ThinkView test preserves table identity after a query edit, and a compiled-CSS check guards the wrapping rule.
• Full-page Chromium reproduction at 1440 and 375px in light/dark mode confirms that a six-column table scrolls at phone width (514px inside a 213px container), long paragraph URLs wrap, and query edits preserve a 140px table scroll position. API responses use fictional fixtures. Safari/WebKit keyboard navigation remains unverified.
• Follow-up CodeRabbit review completed with no findings across the four changed files. The initial review suggested improving pre-existing fenced-code scrolling in CompactMarkdown; that remains outside this fix.

The earlier Meta Muse CI setup failure occurred before tests: the newer workflow referenced an integration directory absent from the old PR head. Rebasing brings that upstream integration into the checkout without changing the typography patch.

Codex investigated the CSS pipeline, implemented the changes and regression tests, generated the fictional response, ran the checks, and drafted this description. Impeccable supplied typography guidance. An independent review using Codex, Claude Code, CodeRabbit, and SonarQube found the table compression and renderer-identity regressions; Codex reproduced and fixed both. The external evie-kit humanizer checked the PR prose. Evie-kit is the contributor's development toolkit for agent workflows and writing checks; no evie-kit configuration was installed in Hindsight.

This is separate from retain-context PR #4751.

A follow-up on related work: I should have checked for duplicate issues and PRs before opening this draft. A search across open and closed issues/PRs for typography, Markdown rendering, prose, Tailwind, spacing, and fonts found no direct duplicate of the missing typography-plugin registration fix, though search is not conclusive.

The relevant earlier work is:

• feat: support markdown in reflect and mental models #307 introduced Markdown support and the manual table styles.
• fix markdown tables in mental models and cosmetic issues  #1800 fixed mental-model table rendering through the compact renderer.
• fix(control-plane): bind the dark: variant to the .dark class #3050 corrected Tailwind's dark-mode variant.
• feat(control-plane): refresh the UI design system #3149 refreshed the control-plane design system, established the current fonts, and deliberately preserved the existing table rules.

This PR retains those fonts, enables the existing typography plugin under Tailwind v4, and replaces the manual table rules with the plugin's styling. The deliberate preservation in #3149 is useful review context: replacing those rules deserves checks across the shared Markdown consumers, including light/dark tables and the compact renderer. The existing browser checks cover Reflect and the rendered compact component; they do not constitute a browser walkthrough of every shared consumer.

I'll continue reviewing this as a focused follow-up to that work. The before/after examples use entirely fictional content.
