Two small pieces of browser finish.

What changes

• The tab names the open page. Every tab read "Maple", so a row of open tabs could not be told apart. The title now leads with the page's own name, then its parent: checkout-api · Services · Maple, Traces · Maple. It reads the breadcrumb trail every page already gives the shell, so no page needed a change and a new page gets a title for free. A crumb that is still loading ("Loading…") is left out, and a route with no page up yet stays "Maple".
• Selected text takes the primary's wash. It was the system blue against a warm palette. The rule sits once in tokens.css (primary-a4), selected text reads in foreground (7:1 on the wash in dark, 12.7:1 in light, so a muted or toned run stays readable while selected), and docs/design-rules.md states it. apps/landing and Maple Local import the same tokens, so they follow; the landing homepage keeps its own scoped rule.

Not in this PR

A favicon that shows firing alerts. The only open-incident count in the shell is read while an alerts page is open, so a badge on every page means widening that live read. That is a separate decision.

Verified

• bunx vitest run src/page/chrome.test.ts src/view.scene.test.ts in apps/web: 7 passed. The new tests cover a detail page, a name still loading, a deep trail, a route with no page, and the not-found route.
• bun run --filter=@maple/web typecheck, bunx oxlint -c .oxlintrc.effect.json --quiet on the changed files, bun run check:tokens: clean.

Summary by CodeRabbit

• New Features
  • Browser tab titles now reflect the current page, including relevant parent pages, while loading pages and unnamed breadcrumb entries are handled cleanly.
  • Selected text now uses a consistent highlight color and contrasting text color across the app.

Walkthrough

The page view now sets document titles from page or not-found breadcrumbs. The base selection style now uses the primary color’s a4 wash, and the design rules describe the selection styling.

Changes: Breadcrumb-based document titles

Layer / File(s)	Summary
Build titles from breadcrumbs apps/web/src/page/chrome.ts, apps/web/src/page/chrome.test.ts	documentTitleOf filters empty and loading labels, then uses up to the final two remaining labels with Maple. Tests cover named, loading, deep, and empty trails.
Use breadcrumb titles in the page view apps/web/src/view.ts, apps/web/src/view.scene.test.ts	titleOf uses page breadcrumbs when a page is open and not-found breadcrumbs for a not-found route. Other routes use only Maple. The document title uses titleOf(model), and tests cover these route cases.

Selected-text styling

Layer / File(s)	Summary
Set the selected-text background packages/ui/src/styles/tokens.css, docs/design-rules.md	The global ::selection rule sets the background to primary-a4 and the text color to foreground. The design rules specify these tokens and prohibit call-site selection: utilities.

Full details: Title check

Explanation

The title names the two main changes: the open page name in the browser tab title, and primary-tinted text selection. Both appear in the raw summary (view.ts titleOf/documentTitleOf in chrome.ts, and the ::selection rule in tokens.css). The title is specific and concise. The 'feat(web)' prefix covers only the web app, but the selection change also touches packages/ui and docs, so the scope is partially narrow. This does not make the title unrelated or vague.

Maple review

🟡 Confidence 6/10 · needs attention. Held at 6 because a correctness warning is open.
_{1 warning −1 · 1 note · tests covered · risk medium}

Names the browser tab from the page's breadcrumb trail and repaints text selection with the primary wash. The title logic is sound and tested; the selection rule needs one fix before merge.

• documentTitleOf builds <page> · <parent> · Maple, skipping a pending crumb
• view's document title now follows titleOf(model) instead of the constant
• ::selection in tokens.css takes primary-a4 behind foreground

Findings

🟠 Warning · F1 · Selected text inside a bg-primary fill drops to 2.1:1 in dark mode

correctness · packages/ui/src/styles/tokens.css:819-820

Forcing foreground on every selection overwrites the dark text that filled primary surfaces use. In dark mode foreground is oklch(0.955) and primary oklch(0.74 0.15 62), so selecting the label of a primary badge (badge.styles.ts:36), a selected choice-card (choice-card.ts:26) or a calendar day washes it to 2.1:1; primary-foreground was 7.9:1.

Keep the wash but exempt primary fills: `.bg-primary::selection, .bg-primary ::selection { color: var(--color-primary-foreground) }`, or pick `primary`/`primary-foreground` as the pair.

🔵 Note · F2 · New rule forbids a selection: utility that native-select.styles.ts still uses

convention · docs/design-rules.md:100-101

The bullet states no call site carries a selection: utility, but packages/views/src/ui/native-select.styles.ts:4 sets selection:bg-primary selection:text-primary-foreground. That select keeps a solid primary highlight instead of the new wash, and a later reader of this rule finds it contradicted in the kit.

Drop the two `selection:` utilities from `native-select.styles.ts`, or narrow the sentence to the primitives that override the token on purpose.
