An expandable carried around 750 characters of classes across its
details, summary, chevron and anchor, repeated for every one on a page.
They now live in `Expandable.css`. `group/expandable` stays a literal
class, since the children's hover and open styles match it by name.

+name: write-pr-description
+description: Write a concise, product-focused PR description from the changes and available discussion. Use when asked for a PR summary or description.
+---
+
+# Write a PR description
+
+Read the full branch diff and commit history against the PR's base branch, not just the latest commit. Use the PR discussion and linked issues for context when available. The PR's changes are the source of truth for what ships if an issue describes something different.
+
+Write for contributors and reviewers who may not know the area. Lead with what changes, prefer user or product impact when supported, and include implementation details only when they help review. Keep the proposed changes short, using bullets only when useful.
+
+Include relevant validation and screenshots when available. Do not claim checks passed unless they ran. Use only information appropriate for a public repository; do not copy private issue details or customer information into the description.
+
+## Template and changelog
+
+Read `.github/pull_request_template.md` immediately before writing. Preserve its required section names and order. Include `Proposed changes` and `Changelog`; omit `Demo` when there is nothing to show. Add optional `Context` before `Changelog` only when it meets the rule below.
+
+Write a short changelog entry describing what shipped. Use `[Feature]` for user-facing additions or improvements, `[Fix]` for user-facing bug fixes, and `[Chore]` for internal maintenance. For features and fixes, say what users can do or what no longer goes wrong in plain words. Keep chores useful to teammates without inventing user impact. Remove unused examples and placeholders. Usually one entry is enough; use more only for distinct changes. The PR changelog does not replace any changeset required by `AGENTS.md`.
+
+## Optional context
+
+Write `Proposed changes` and `Changelog` first. Add `Context` only when it tells someone unfamiliar with the area something material that the changelog does not. `Problem` names a concrete failure or limitation supported by the PR or discussion. `Outcome` names what this PR delivers at its actual scope. Omit the section if either field would repeat the changelog, describe only implementation, or guess at an impact.
+
+```markdown
+## Context
+
+**Problem:** <concrete failure or limitation>
+
+**Outcome:** <result delivered by this PR>
+```
+
+Keep each field to 1–2 short, non-technical sentences. Prefer user or product impact when supported. For infrastructure changes, explain the failure or limitation they caused. Do not invent an actor, customer segment, ownership, or impact, or force the change into a user story. Do not turn a preparatory change into a claim that the whole workflow is fixed. Keep the roles distinct: `Context` explains why this matters, `Changelog` says what shipped, and `Proposed changes` can explain implementation.
+
+Examples:
+
+- A dependency bump with no demonstrated user effect needs no `Context`.
+- If creating the first change request leaves the user on an empty screen, say that it now opens after creation. Leave the animation-listener details in `Proposed changes`.
+- If a PR indexes links for later checks, describe the indexing result. Do not claim every link has already been checked.
+
+## Writing pass
+
+- Use plain words and direct verbs: "use" instead of "leverage", "help" instead of "facilitate". Prefer active voice when the actor is known.
+- Name the concrete behavior instead of saying "improves the experience" or "makes it more robust". Support performance claims with measurements.
+- Cut filler, promotional language, and generic conclusions. If a sentence could fit almost any PR, make it specific or delete it.
+- Keep one idea per sentence and use consistent names. Remove redundant hedging without hiding real uncertainty.
+- Avoid "not just X, but Y", forced groups of three, em dashes, decorative emojis, and unnecessary bold text.
+
+Return the description in a Markdown code block unless asked to update the PR. When asked to update it, apply the description with `gh pr edit` using a body file.

-A near-white tint color (e.g. a warm `#F5F3EF`) is now taken as the exact page background, mirroring the existing behavior for near-black tints. The tint's exact lightness, hue and chroma are preserved, and the color is anchored to whichever scale step the active theme renders as the background — so it matches exactly on `muted` (which uses the second step) as well as `clean`. This applies only to near-neutral tints that are light enough to read as a background; saturated or merely light-ish colors keep their normal accent scale. The `bold` theme is unaffected: it already uses the tint for the header and stays intentionally two-tone.

-Fix the docs embed not applying `?theme=light`/`?theme=dark`. The theme was dropped when the embed redirected to its default tab, and the embed tabs couldn't read it because they render statically (their request headers are empty). The middleware now threads a forced embed theme through the embed route context (scoped to the embed, not the main site), so the embed tabs honor it while staying statically rendered, and the redirect forwards it to the default tab. The forced theme is also persisted to the embed's own theme storage so it is remembered across tab navigation instead of only applying while the query string is present.

-Sync the API reference responses selector with the "Responses" collapsibles, and keep the selected response in sync across every operation on the page (like the code sample language selector). Selecting a status code now expands the matching response section and applies to all operations at once.

-Fix a light/dark flash on published sites configured to respect the system default (no theme toggle). Such sites forced the `system` theme, but `next-themes`' pre-paint script applies a forced value verbatim without resolving `prefers-color-scheme`, so the page painted light and only switched to dark after hydration. We now leave the theme unforced when the default is `system` (only concrete light/dark themes are forced), letting `next-themes`' existing pre-paint script resolve the system preference before first paint.

-Fix the docs embed widget shipping a stale script: declare the embed package's `standalone/` bundle as a Turbo build output. Because it wasn't declared, changes confined to the standalone widget (which compiles to `standalone/` but not `dist/`) didn't invalidate the downstream `generate` cache that copies it into the app, so the deployed widget could lag the source — e.g. the `clipboard-write` permission on the widget iframe never reached production, breaking the copy button in the Assistant embed.
