feat(home): add recently played row with separator

[theoneand33]

Adds Recently played section backed by localStorage, with separator before the full grid. Separator lives inside the hidden section so it only shows when history exists.

📝 Walkthrough

Walkthrough

The change tracks visited games in localStorage and displays up to 10 validated entries on the index page. It removes duplicate games, limits stored history, renders linked cards, and ignores invalid data or storage errors.

Changes

Recently played games

Layer / File(s)	Summary
Game history tracking src/layout/layout.astro	The game-page script validates the current game, updates the recently-played list, removes duplicate slugs, limits the list to 10 entries, and handles storage errors.
Recently played rendering src/pages/index.astro	The index page validates stored entries, renders linked game cards with lazy-loaded images, reveals the section when cards exist, and ignores parsing or rendering errors.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 8e2f9

Recently played history can show games that are no longer available, sending users to invalid game links. Validate stored entries against the current game list before merging.

Clean, minimal implementation of the Recently Played row. Correctly scoped, matches project conventions.

What it does

• layout.astro: records {s, t, i} to localStorage["recently-played"] on each game page, MRU-deduped, capped at 10. Guarded by seo && slug, so it covers all games (all route through [slug].astro, including run-3/webtris).
• index.astro: hidden <section id="recent"> rendered from localStorage (max 10), unhidden only when tiles render. Separator <hr> lives inside the section, so it only shows with history — as described.

What's good

• Static-first preserved: no server, DB, or dependency. Two small is:inline scripts, no layout shift (section starts hidden).
• Tile markup replicates gametile.astro classes exactly (m-5, aspect-[3/2], max-w-[300px], lazy/async img) — visually consistent.
• Safe DOM construction: textContent for titles, a.href = "/games/" + g.s (prefix prevents javascript: escape), field validation (g.s/g.t/g.i), try/catch around localStorage (private-mode safe).
• AGENTS.md compliant: no per-game pages, no Ruffle/SEO changes, absolute asset paths in stored data.

Nits (non-blocking)

• Stale entries: title/image/slug are denormalized with no check against gamesMap. A removed/renamed slug renders a dead link forever. Consider storing slugs only, or filtering obviously malformed slugs on read.
• a.href = "/games/" + g.s could use encodeURIComponent(g.s) for hygiene against slugs with spaces/quotes in poisoned localStorage.

No check/lint run (bun unavailable in this environment); change is formatting-clean by inspection and matches existing Prettier style.

In `@src/pages/index.astro`:
- Line 59: Update the recently-played filtering logic around the guard checking
g.s, g.t, and g.i to also require that the entry’s slug exists in the current
allowed game slugs or canonical card data. Serialize that data into the client
script and skip entries absent from it, preventing links to removed game routes
while preserving valid entries.

Clean, minimal implementation. The follow-up commit ad683df correctly addresses the CodeRabbit stale-slug finding.

What it does

• layout.astro: on game pages (seo && slug), prepends {s, t, i} to localStorage["recently-played"], MRU-deduped, capped at 10, all in try/catch (private-mode safe).
• index.astro: hidden <section id="recent"> hydrates from localStorage, validates fields + allowlist (valid.indexOf(g.s) where valid = defaultGames via define:vars), builds tiles with safe DOM APIs, unhides only if tiles render. <hr> inside section so separator only shows with history.

What's good

• Static-first preserved: no server, DB, or deps. ~60 lines, two small is:inline scripts.
• AGENTS.md compliant: no per-game pages, no Ruffle/SEO changes, absolute paths (/games/, stored /images/...).
• Tile markup replicates gametile.astro exactly (classes, 300x200, lazy/async, data-astro-prefetch) — visually consistent.
• Safe: textContent for titles, "/games/" + g.s prefix + allowlist check kills javascript:/dead-link risk, field validation + try/catch handles corrupt storage, starts hidden so no layout shift.

Nits (non-blocking)

• define:vars={{ valid: defaultGames }} injects a generic global valid. Rename to validSlugs to avoid collisions.
• Titles/images are denormalized at visit time — a renamed cover shows stale data until revisit. Canonical render from gamesMap would fix, but low impact.
• Minor inconsistency: layout.astro uses JSON.parse(getItem(k)) || [], index.astro uses || "[]" — both safe, pick one style.

No blocking issues.
