fix(ui): status and secondary text clear 4.5:1, light warn leaves the primary hue - #2483
A design pass over the dashboard found that status colours and the quietest text step were below 4.5:1, and that in the light theme the warn colour sat 15 degrees of hue from the primary, so a warn bar read as the same orange as a button or the selected row.
What changed
A tone as text is its ink. A tone's fill is tuned to be seen as a bar or a dot, which on white leaves it near 3:1 as type. text-primary, text-severity-*, text-success, text-warning, text-info and text-sidebar-primary now resolve to a deeper step of the same hue through the --text-color-* theme keys. No call site changes. Fills, borders and strokes keep the tone. In dark the inks are the fills, except trace (reads muted-foreground) and fatal (was 3.4:1).
Light severity-warn is a yellow (oklch(0.73 0.165 88)), about twice as far from the primary as before and close to the separation the dark theme already had.
foreground-subtle clears 4.5:1 (a 94% mix, was 70%) on the page, a card and the selected-row wash, and light muted-foreground is one step deeper so the mix can get there. It was 3.3:1 in dark and 2.8:1 in light while carrying units, dates, counts and column labels. foreground-faint stays near 2:1 for separators; the log timestamp fraction, the trace timeline hints and one placeholder moved off it.
surface-strong is 90% of muted (was 60%). It could not be told from surface-sunken (50%), which the hover and pressed rules rely on.
Severity text set through a style object reads the ink (getSeverityInk): log level labels, the log severity badge, the investigation severity chip.
Marks that were coloured through a text class keep the tone: the Maple mark takes the brand orange, the error trend bars their severity fill.
Google Cloud list: the volume column head ("Requests", "Delivered", "Queries") was hand-rolled at 11px sentence case; it now uses the kit table-head type like its neighbours.
DESIGN.md said there are no shadows, named a chart library that is no longer a dependency, three texture classes that no longer exist, and a warn colour "the same hue as primary on purpose". It now matches tokens.css and docs/design-rules.md, which gains the ink and subtle rules.

What is left is separator dots, per-service data colours on the trace timeline, and chip keys that step back from their value on purpose.
The screenshots below were taken at a 90% subtle mix; a review comment raised it to 94%, a hair brighter.
Layout is unchanged: text geometry on the re-rendered pages matches node for node, apart from the Google Cloud table head, which is 7px shorter.

An independent review of the diff confirmed in the Tailwind source that text-* resolves --text-color-* before --color-*, with variants and opacity modifiers, and that no other utility reads that namespace
Not in this PR
Line-heights for the sizes under 12px. They inherit, so the same 10px label renders at four different line-heights. Giving them their own was tried and taken out: rows that rely on a tight parent grew about 5px each (the infra overview by 198px). It needs each of those sites to name its leading first.
The sidebar "Infrastructure" label truncating beside its brand marks, the 64px top bar, and sentences set in mono where the type rule asks for the prose face. These are design calls, not fixes.
… primary hue
A tone's fill is tuned to be seen as a bar or a dot, which on white leaves it
near 3:1 as type. Each tone now has an ink: text-primary, text-severity-* and
the status aliases resolve to it through the --text-color-* theme keys, so no
call site changes. In dark the inks are the fills, trace and fatal aside.
- Light severity-warn moves to a yellow (hue 88): it sat 15 degrees from the
primary and read as the same orange as buttons and the selected row.
- foreground-subtle is 90% of muted-foreground, and light muted-foreground is a
step deeper, so the last text step that carries information clears 4.5:1.
- surface-strong is 90% of muted: at 60% it could not be told from
surface-sunken (50%).
- Severity text set through a style object reads the ink (getSeverityInk).
- Marks that were coloured through a text class keep the tone: the Maple mark
takes the brand orange, the error trend bars their severity fill.
- The Google Cloud volume column head uses the kit table-head type.
- DESIGN.md no longer contradicts tokens.css and design-rules.md.
This PR adds severity text-ink tokens and updates their use across UI components. It also changes foreground and brand styling, standardizes a table header, and revises design documentation for colors, typography, surfaces, and interactions.

Summary
Text-ink tokens and foreground rules packages/ui/src/lib/severity.ts, packages/ui/src/styles/tokens.css, docs/design-rules.md
Adds severity ink mappings and theme text-color tokens. The design rules define tone text utility usage and clarify the roles of subtle and faint foregrounds.
Severity styling in components apps/local-ui/src/page/logs/view-patterns.ts, apps/web/src/page/errors/hub/view-signal.ts, apps/web/src/page/investigations/conversation/kit/*, apps/web/src/page/agent-sessions/session/view-overview.ts, packages/views/src/logs/*, packages/views/src/ui/logs/*
Severity labels and charts use ink colors for text. Severity fills and borders continue to use fill colors. Error backgrounds use the shared alpha utility.
Components adopt updated foreground and primary wash utilities. Maple marks use the brand color, and the GCP volume header uses the shared table-header renderer.

Include CRITICAL in the solid-chip exception.
The log row renders both FATAL and CRITICAL as solid chips with text-on-fill. The rule excludes CRITICAL, so readers could implement that label differently. Update the exception to include it. (raw.githubusercontent.com)

Document the existing pulse animations.
The provenance loader and service-map loader still use pulsing dots. The service-map animation is disabled for reduced motion. “Nothing pulses” therefore gives an incorrect account of the current motion behavior. Document these exceptions or remove the animations. (raw.githubusercontent.com)
