 # Buzz Sheet
 
 Buzz Sheet is a Thai-first guide CMS for turning structured character, build,
-team, rotation, and comparison data into responsive game-guide pages. Authors
-work in a visual block editor; visitors get readable guides rather than a
-spreadsheet interface.
+team, rotation, and comparison data into responsive game-guide pages.
 
 Production target: `https://guide.sudloh.com`
 
 ## Included capabilities
 
-- Searchable character directory with element and role filters.
-- Unlimited character pages with custom slugs, ordering, notes, and visibility.
-- Visual admin workspace with inline editing, inspector, preview, keyboard and
-  pointer reordering, 750 ms autosave, conflict recovery, and revisions.
-- Six reusable templates covering classic guides, rotations, one-page builds,
-  multi-role builds, team databases, and calculation-backed comparisons.
-- Validated block schemas with migrations and a safe fallback for unknown
-  future block types.
-- Restricted decimal formula engine with named references, dependency ordering,
-  cycle detection, typed failures, and presentation-only rounding.
-- Read-only comparison charts with visible values and accessible table fallbacks.

+- Structured editors for overview, weapons, artifacts, constellations, teams,

 - Better Auth email/password login with administrator-managed accounts.
 - Private S3-compatible media uploads with reference-aware same-origin delivery.
-- PostgreSQL transactions, immutable data-source versions, revisions, and a
-  retryable outbox.
