Add NBA mirror

[lyc61c]

Summary

Adds a new WebHarbor mirror site for NBA.com:

• Real site mirrored: NBA.com
• Upstream URL: https://www.nba.com/
• Site slug: nba
• Local port: 40015 in the container, typically exposed as http://localhost:41015/ during testing

The mirror implements an NBA.com-style sports information portal with homepage stories, games/schedule, playoffs, draft, fantasy, stats, standings, teams, players, news/articles, search, tickets, store/cart/checkout, and account flows. Runtime behavior is deterministic and uses SQLite plus local static assets only.

Seeded data

Major seeded model counts:

Model	Rows
Users	4
Teams	30
Players	28
Games	10
Articles	22
Products	16
Cart items	8
Orders	4
Order items	4
Favorites	12
Ticket requests	0

Functional coverage

Implemented routes and flows include:

• NBA.com-style homepage with top game strip, hero story, story cards, headlines, trending/news sections, recaps, and right rail
• Games and schedule pages with official-style game cards and playoff schedule layout
• Playoffs bracket/news page
• Draft page with combine, lottery, mock draft, key dates, draft info, and classic moments sections
• Fantasy page with featured stories, watch cards, Yahoo High Score sections, and dense player-stat table
• Stats and standings pages with official-style leader panels, tables, conference standings, and bracket context
• Teams by division, team profiles, rosters, schedules, and team stats
• Players table, filters, player profiles, and stat summaries
• News/category browsing and article detail pages
• Search grouped by teams, players, games, articles, stats, and store items
• Tickets request flow, local NBA Store, bag, checkout, account, orders, and favorites

Benchmark tasks

sites/nba/tasks.jsonl contains 20 WebVoyager-schema benchmark tasks.

Task coverage includes:

• Player filtering and profile lookup
• Games and season leader comparison
• Schedule lookup
• Standings-to-team-profile reasoning
• Player stats and team stats comparison
• Team division browsing
• Draft page/article/key-date tasks
• Fantasy stat table comparison
• Search-to-article navigation
• Watch/highlights disambiguation
• Tickets comparison
• Store filtering/product-detail reasoning
• Authenticated cart/checkout/account update flows

The tasks were revised to reduce benchmark leaks:

• No repeated seeded credential text in tasks
• No alice.j@test.com / TestPass123! task leakage
• No stale TBD arena task from an older schedule layout
• Fewer login-dependent tasks; only tasks that genuinely require account/cart/profile state ask the user to sign in

Paired HuggingFace dataset PR

Paired asset-side PR:

<PASTE_HUGGINGFACE_DATASET_PR_LINK_HERE>

The HF asset bundle is nba.tar.gz and contains:

• nba/instance_seed/nba.db
• nba/static/images/
• nba/static/external_cache/

After the HF PR merges, this code PR should bump .assets-revision to the merged dataset revision.

Visual fidelity

The NBA mirror is designed to closely follow NBA.com rather than a generic Bootstrap demo:

• Dark NBA-style top navigation with major nav entries: Games, Schedule, Watch, Playoffs, News, Draft, Stats, Standings, Teams, Players, NBA Play, Fantasy, BAL 2026, League Pass, Store, Tickets, Sign In
• Homepage portal layout with top score strip, hero story module, story grids, headlines rail, trending sections, game recaps, Around the NBA content, social/affiliate-style right rail sections
• Schedule, Draft, Fantasy, Playoffs, Stats, and Standings pages modeled after NBA.com page structures
• Teams grouped by NBA divisions with local profile/stats/schedule/roster links
• Dense player/stat/standings tables for benchmark comparison tasks
• Local NBA.com-style imagery served from static/images/; no runtime network fetches

Screenshot evidence to attach to this PR:

• NBA.com homepage vs local http://localhost:41015/
• NBA.com Schedule page vs local /schedule
• NBA.com Draft page vs local /draft
• NBA.com Fantasy page vs local /fantasy
• NBA.com Playoffs page vs local /playoffs
• NBA.com Stats page vs local /stats
• NBA.com Standings page vs local /standings

Notes for reviewers

• The mirror does not implement real video streaming, League Pass playback, ticket purchasing, payment processing, or external authentication.
• Tickets, store, checkout, favorites, and account flows are local deterministic benchmark workflows.
• HTTP handlers use SQLAlchemy/SQLite and local static files.
• The runtime does not depend on live NBA.com data or runtime JSON files.
• sites/nba/image/ is a local scratch/reference directory and should not be included in the final GitHub PR.
