Shared-account ebook store & serial fiction platform
Two separate products, two separate databases — a pay-once ebook store and a coin-based serial fiction platform — sharing one login so a reader signs in once and uses both.

Overview
A single authentication layer — one account, one password — sits in front of two independently built products: a pay-once ebook store and an episodic web fiction platform, each with its own database and its own engineering problems.
Ebook store — readers
Reader
Browse, preview, and buy
Category filters, live search, a dedicated bestsellers view, and real PromptPay checkout — QR generation with cent-level amount tweaks to prevent order collisions, confirmed automatically via a real bank webhook, not a mocked screen.
Reader
Free previews, real formats
The first 3 chapters (EPUB) or 3 pages (PDF) are cut server-side before the file ever leaves the server. Two dedicated readers — paginated EPUB and zoom/pan PDF — preserve original layout so Thai fonts never break on conversion. Installable as a PWA or a real mobile app via Capacitor.
Ebook store — publishers & admin
Publisher
Manuscript upload portal
Publishers upload EPUB/PDF with cover art and a built-in crop tool, set their own price and category, and submissions sit in a review queue before going live.
Admin
Commission & moderation
Full catalog control with delete protection for already-purchased titles, per-publisher commission rates (default 70/30), user management with forced-reset temporary passwords, and separate audit logs for logins and admin actions.
Engineering
Resilient by design
Redis caching on high-traffic pages with automatic DB fallback if Redis goes down, a store-wide feature flag that removes routes entirely when disabled (not just hides them), and a pre-launch access-code lock that reveals nothing about the catalog to outsiders.
Fiction platform — readers & writers
Reader
Thai-aware search & coin unlocks
Search tuned specifically for Thai character ordering, auto-saved scroll position to resume exactly where you left off, and a coin-unlock system with a full transaction ledger that prevents double-spending or negative balances during simultaneous unlocks.
Writer
Scheduled publishing & pricing
A rich-text editor with inline images (drag-to-resize from the corner), publish-ahead scheduling that releases chapters automatically with no separate background worker, per-chapter coin pricing (0 = free), and a Thai-aware word count that counts characters instead of whitespace-delimited words.
Fiction platform — admin
Admin
Content moderation & dashboard
Totals across stories, chapters, priced chapters, readers, and coins spent; suspend/restore problem stories and edit any chapter's content or price directly.
