docs(site): add changelog entry 2026-08-28 and restore changelog code highlighting

[ankur-arch]

What

Adds the external changelog entry for 2026-08-03 to 2026-08-28 at apps/site/content/changelog/2026-08-28.mdx, plus four screenshots under apps/site/public/changelog/2026-08-28-*.png.

Generated with content-write-changelog from the same PR set Loggy extracts (all loggy-core repos, ~580 merged PRs). Loggy's Doppler project was not reachable from this machine, so the extraction was reproduced with gh against the same topic discovery and merged-PR search.

Structure, after editorial review: single-claim headline, three headline changes (Compute GA, Deploy Buttons + apps directory, Prisma 8 via prisma@latest), what existing users need to do, breaking changes, per-product detail, fixes, guides, and an "Around Prisma" section for Builder's Day and Prisma Arcade with brand CTAs.

Site fix included

The rebranded changelog page (apps/site/src/app/changelog/[slug]/page.tsx) renders MDX through next-mdx-remote with no rehype plugins, so no entry has had syntax highlighting in production (check any <pre> on www.prisma.io/changelog/2026-08-02). This PR:

• adds fumadocs' rehypeCode (shiki, github-light/github-dark as --shiki-* vars, same as the docs app) and matching prose CSS in globals.css;
• registers PrismButton / PrismButtonOutline as MDX components so entries can use brand CTAs;
• removes Typography's literal backticks around inline code in .prose.

Verified with a production build: 2026-08-02 goes from 0 to 42 styled spans, 2026-08-28 has 99.

Review focus

• Positioning: Compute GA (docs: drop Prisma Compute beta/RC framing now that Compute is GA #8195, Console launch banner), Prisma 8 as the 8.0.0 rc line under latest, Composer Early Access.
• Included-request numbers follow /docs/compute/pricing and fix(site): add free tier limits to pricing #8166 (Free 1M / Starter 5M / Pro 20M / Business 100M). pdp-control-plane#4948 lists 100k / 1M / 10M / 50M. Please confirm which is live.
• The "classic builds paused after cutoff" note (pdp-control-plane#4996/Docs: beforeExit hook only applies to BinaryEngine #4998) is config-gated by COMPOSER_ROLLOUT_* dates. Drop it if no cutoff is scheduled.
• Screenshots were taken from a personal workspace; project names in the usage chart are mine. Swap for a cleaner workspace if preferred.
• Builder's Day copy omits the price since the early bird window closed on August 23.

Triage notes

No public PR (private repos, effect published): Compute GA and pricing enforcement (#4994, #4948, #4952, #4958), Console usage dashboards (#4980, #4988, #5013, #5014, #5021), Deploy Button (#4770, #4928), templates/apps directory (#4806, #4810, #5000, #5019), one-box project creation (#4883, #4916), builds pages (#4860, #4830), GitHub permission preflight (#4857, #4945), Composer support boundary (#4966, #5009), awaiting-first-deploy card (#5052), connect already-configured repo (#5034), REST API additions (#4774, #4785, #4823, #4855, #4886, #4978), MCP OAuth fixes (#4815, #5008), backup size fix (#4887), rollout notice (#4996, #4998), Spark runtime hardening (project-compute #119, #130, #131, #139).

Flagged, not included: application topology visualization (pdp-control-plane#4898, #4997; unclear whether the mercury gate is off for it); Prisma Postgres v2 boot regions, archival restore, daily backup cadence (pdp-cloudflare#2360/#2363/#2366, #2338, #2367; no announced surface); Alchemy deploy-state API (#4816, #4817; undocumented); Object Store regional buckets (#4804); Console account/OAuth migrations, marketplace refund endpoint, marketplace spend limits (#5059, #5060, #4812, #4794).

Excluded (internal): all pdp-metal, inf-ppg-infrastructure, and remaining pdp-cloudflare PRs; Spark seccomp/port-takeover internals; ORM CLI engine ports, ADRs, roadmap, coverage, release bumps, dependency bumps, CI; web site mechanics (OG images, banners, redirects, analytics, cookieless PostHog, privacy policy, code of conduct, "preferred on Google" button, author avatar).

Demo snippets to confirm: prisma.config.ts (prisma/orm#30058), Composer service.ts (/docs/composer), @@check (prisma/orm#29972), Deploy Button URL (/docs/compute/deploy-button).

Linear: none provided; add before merge if required.

Changes

Changelog publication

Layer / File(s)	Summary
Release changelog document apps/site/content/changelog/2026-08-28.mdx	Updated release notes for Compute, Deploy Buttons, Prisma 8, REST API features, fixes, guides, and community events.
MDX rendering configuration apps/site/src/app/changelog/[slug]/page.tsx	Configured Fumadocs and Shiki highlighting with plaintext fallback. Registered Prism button components for changelog MDX.
Theme-aware code-block styling apps/site/src/app/globals.css	Added light and dark styles for Shiki code blocks. Removed generated backticks from inline code elements.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🔵 Low · up to 15199

The changelog may overstate Compute usage reporting and incompletely describe Deploy Button behavior and requirements, which could mislead users following the release notes or setup guidance. The risk is localized and mergeable with explicit owner awareness or a follow-up documentation correction.

In `@apps/site/content/changelog/2026-08-28.mdx`:
- Line 37: Update the changelog entry to remove the claim that the Prisma
Console shows all four meters per day broken down by app and response status;
retain only the currently available Workspace Overview and billing-view Compute
reporting statements.
- Line 23: Update apps/site/content/changelog/2026-08-28.mdx at lines 23-23 to
state that deployment provisions the resources declared by the selected app’s
Composer module, without promising a Prisma Postgres database. At lines 43-43,
remove the unconditional Prisma Postgres database claim.
- Around line 59-61: Update the Prisma 8 dependency guidance in the changelog to
clarify that the single package refers only to the ORM facade, while a
PostgreSQL project still requires local prisma and `@prisma/orm-postgres`
dependencies for the prisma.config.ts setup.
