tokens.css defined colours, radii and font families but not a single --text-*
step, so font sizes had no baseline to align to and grew wherever they were
needed: 51 distinct sizes across web + desktop, 370 written as arbitrary
values, six at half a pixel (10.5 / 11.5 / 12.5 / 13.5 / 14.5 / 15.5px).
text-xs and text-sm carried nearly all UI text while the range between them —
11, 13, 15px — could only be reached with arbitrary values. Hierarchy does not
come from having more sizes; past a handful, each extra size makes the
hierarchy blurrier.
Add ten role-named steps, each with its own line-height so leading cannot
fragment the way size did, and move every product-UI call site onto them.
Steps are named for what the text is for, not for a t-shirt size, because
that is what keeps the scale from drifting again.
Six steps deliberately keep the exact size/line-height pairs of the Tailwind
defaults they replace, so the ~1,900-call-site rename moves nothing on screen.
The visible changes are confined to former arbitrary values snapping to a step:
8/9/10px -> micro (11px) on badges and overlines; 17 -> 18; 22 -> 24; 30
(text-3xl) -> 36 on headings and stat numbers; 12.8px -> label (13px) on small
buttons and toggles. Half-pixel sizes are gone.
This supersedes #6108, which was reverted by #6116 because the sidebar group
labels rendered at the inherited 16px. The cause was not the scale but cn():
`text-<x>` is ambiguous in Tailwind, and tailwind-merge resolves it against a
table listing only the default sizes, so it filed every role step under
text-colour and dropped whichever of `text-caption` /
`text-sidebar-foreground/70` came first. Registering the steps as a font-size
class group restores the real conflict groups — size beats size, colour beats
colour, the two coexist — and a test pins the list against the scale, since
the failure is silent in source.
Hand-written CSS is covered too. The transcript kept a 12.5px body long after
every Tailwind call site was on the scale, so the "no half-pixel sizes" claim
was true of the classes and false of the product; the editor's prose, code and
mermaid ramps had the same blind spot, and seven of their eight values already
equalled a step exactly. All now reference var(--text-*). The guard test reads
raw `font-size:` declarations as well as class names, exempting only the 16px
iOS input-zoom workaround in base.css and the landing pages' marketing ramp.
apps/mobile (own NativeWind config) and apps/docs (fumadocs' own type system)
keep Tailwind's default scale and are untouched. Landing display type
(rem/clamp, 2.2-6.4rem) stays on its separate ramp, as do four decorative
emoji / serif-hero sizes.
Verified on a running local stack: pinned sidebar rows and group labels
measure 12px/16px, nav items 14px/20px — identical to pre-migration. An audit
of every rendered font size across the product surfaces finds nothing off the
scale; the only exceptions are avatar initials and emoji, which
actor-avatar.tsx sizes proportionally to the avatar diameter by design.

tokens.css defined colours, radii and font families but not a single
--text-* step, so font sizes had no baseline to align to and grew wherever
they were needed: 51 distinct sizes across web + desktop, 370 of them written
as arbitrary text-[Npx] values, six at half a pixel (10.5 / 11.5 / 12.5 /
13.5 / 14.5 / 15.5px). text-xs and text-sm carried nearly all UI text while
the range between them — 11, 13, 15px — could only be reached with arbitrary

Six steps deliberately keep the exact size/line-height pairs of the Tailwind
defaults they replace, so the 1,900-call-site rename (text-sm -> text-body
and friends) moves nothing on screen. The visible changes are confined to
former arbitrary values snapping to a step:
- 8 / 9 / 10px -> micro (11px): 102 sites, mostly badges and overline
labels. Deliberate — under 12px is a counter role, not a text role.
- 17px -> title (18px), 22px -> display-sm (24px), 30px (text-3xl) ->
display (36px): 21 sites, all headings or stat numbers in flexible
containers.
- Half-pixel steps are gone entirely.
Arbitrary sizes also inherited whatever line-height was above them; the
tokens now pin one, which removes latent overflow risk in the fixed-height
h-4/h-5 badges those sizes were used in.
apps/mobile (own NativeWind config) and apps/docs (fumadocs' own type system)
keep Tailwind's default scale and are untouched. Landing-page display type
(rem/clamp, 2.2-6.4rem) is marketing typography on a separate ramp and stays
out of the scale, as do four decorative emoji / serif-hero sizes.
A guard test fails the build on any font size written outside the scale,
reporting file:line — without it nothing in a Tailwind build makes an
off-scale value look wrong, which is how the drift happened.
Verified against a local stack: typecheck, lint and the full TS suite show no
new failures, and before/after screenshots of issues, issue detail, runtimes
(populated), usage, agents, inbox, my-issues and settings differ only in the
intended 10px -> 11px labels, with no row-height, truncation or layout shift.

HTML attachment previews mount the document inside a sandboxed
`<iframe srcdoc>` deliberately WITHOUT `allow-same-origin` — uploads are
untrusted user content. Chromium treats fragment-link clicks inside such an
opaque-origin srcdoc iframe as cross-origin frame navigation and silently
rejects them, so clicking a TOC entry never scrolls.
Append a tiny shim script to the srcdoc that intercepts `<a href="#...">`
clicks inside the iframe and calls `scrollIntoView` directly. The shim runs
in the iframe's own opaque origin under `allow-scripts` — no new
capabilities, no sandbox token changes; it cannot reach parent / cookies /
localStorage.
All three HTML attachment surfaces share the same helper:
- inline 480px card (html-attachment-preview.tsx)
- full-screen modal (attachment-preview-modal.tsx)
- full-page route (attachment-preview-page.tsx)

* fix(editor): bump hast-util-to-html to v9 so lowlight output actually serializes
Source view of fenced ```html (and any other code block falling through to
the lowlight branch in ReadonlyContent) silently rendered as un-highlighted
escaped text. Root cause was a stale dep pin: `hast-util-to-html: ^4.0.1`
predates the package's ESM/named-export rewrite — v4 only exports a CJS
default function, so the `import { toHtml } from "hast-util-to-html"` in
code-block-static.tsx:19 and readonly-content.tsx:32 resolved to
`undefined` at runtime. The try/catch in both call sites caught the
"toHtml is not a function" throw and fell through to escapeHtml plain
text, so no `.hljs-*` spans ever made it to the DOM and the syntax-color
CSS added in #2808 had nothing to attach to.
Bumping to ^9.0.5 (matches the v9 line that lowlight@3 / remark / rehype
ship in the rest of the tree) makes the named `toHtml` export available
and source-view highlighting works.

* feat(editor): open HTML attachment in new tab + full-page preview route
Adds a third toolbar button to HtmlAttachmentPreview between Maximize and
Download: open the attachment in a new app tab (desktop) or browser tab
(web). The full-screen modal stays — they serve different scenarios:
modal for a quick "see it bigger" without leaving the issue context,
new-tab when the user wants to keep the rendered HTML around while
working on something else.
Components:
- New workspace path: `/{slug}/attachments/{id}/preview?name={filename}`.
Lives outside the (dashboard) group on web so the iframe gets the full
viewport — sidebar would defeat the point. Desktop registers the route
inside `WorkspaceRouteLayout` so workspace context resolution still
runs (no slug → no path is built).
- `packages/views/attachments/attachment-preview-page.tsx`: shared full-
page view that reuses `useAttachmentHtmlText` for the iframe srcDoc.
Sandbox stays `allow-scripts` (no allow-same-origin) — same security
posture as the inline preview.
- `HtmlAttachmentPreview`: adds Open-in-new-tab button. Routes through
`useNavigation().openInNewTab` when available (desktop), falls back to
`window.open(getShareableUrl(path))` on web. Button is hidden when no
workspace slug is in scope (shouldn't happen in practice, but the
shared component must not throw outside a workspace route).
Tests cover: desktop openInNewTab call args, web window.open fallback,
and that the failure-mode toolbar still surfaces all three actions.

* fix(editor): drop now-stale @ts-expect-error on hast-util-to-html imports
v9 ships bundled type declarations, so the directives added for v4 trigger
TS2578 ("Unused '@ts-expect-error' directive") on CI typecheck.
