// From zero to deployed -- backends, frontends, AI integrations, and everything in between.
// If it thinks, automates, or integrates -- I'm the one building it.

TITLE  : THE HARVEST OF MINDS -- ECOS, VOL. 1
         (A Colheita de Mentes)
GENRE  : Cyberpunk / Science Fiction
SETTING: Dicotomia -- a dystopian megacity split between neon-drenched lower city and corporate heights
STATUS : PUBLISHED

Exploring memory, power, and forced evolution through a cast of augmented outcasts.

Play tabletop RPGs with an AI game master that narrates, remembers the campaign, and rolls real dice. Open source, bring-your-own-key.

• Multi-provider -- Gemini, OpenAI, Ollama or LM Studio behind one interface; runs fully local if you want it to.
• Persistent saga memory -- rolling summarization folds old turns into long-term memory so campaigns survive context limits.
• Voice mode -- speech in, narrated speech out, over a WebSocket stream.
• Real dice -- the model emits [[ROLL:1d20+5]] tags resolved by code, so it can never invent a number.

AI-powered deck construction tool -- Gemini 2.5 Pro as the backbone.

• Generates complete 60/100-card decklists from user parameters (format, power level, playstyle, colors, commander).
• RAG loop -- Gemini calls a local searchLocalDatabase tool to verify card legality and prices mid-generation.
• Deck upgrade analysis -- paste a list, get 6-12 prioritized 1-for-1 swap recommendations.
• Full auth (JWT), card hover tooltips, deck vault, AI upgrade sidebar.

Mission control for money: personal budgets, savings goals and business invoicing in one dark-first cockpit.

• Accounts, transactions, budgets, goals and recurring expenses, split across personal and business scopes.
• Client directory, invoicing and line items for the freelance side of the ledger.
• Shared single sign-on with the rest of the platform; every query scoped by owner.

The experience of online shopping, without spending real money.

• Thousands of real products across four parody marketplace skins, with a full cart and "checkout" flow.
• Hard safety invariant -- no payments, no personal data, no real purchases, enforced by a connect-src 'self' CSP that blocks every off-origin request at the browser level.
• Offline-capable: ships with a bundled catalog seed and needs no external API to run.

Paste a URL, get a short link and its QR code in one step. No account, no ads, no tracking pixels.

• Custom aliases, click counts, and a delete token that is the only proof of ownership (no accounts to breach).
• Generated share cards name the real destination, because a shortener that hides where it goes is a phishing tool.
• Rejects every scheme but http/https, rate limited per address.
