Editable PPTX decks from a brief - rendered, gated, and assembled by a local engine your coding agent drives

Who this is for: you already use a local coding agent (Claude Code, Codex, Cursor, OpenCode) and make reports or decks often, and you want brief -> validated slides -> editable PPTX to be repeatable.

Not for you if you want a site that turns one sentence into ten finished slides. This engine renders, gates, and assembles. You (or your agent) author the HTML pages from a bundled master.

What you get

• 6 production design masters (terminal-operations, wave-analytical, paper-ink, institutional-methodology, philosophical-workshop, investment-blue), each a self-contained HTML with 16 layout primitives.
• Deterministic QA gates: headless-Chromium render, density gate (24-band coverage and dead-zone detection), style-consistency gate (color/font/token drift).
• Half-editable PPTX: native text boxes and vector shapes; only complex charts rasterize to 3x PNG.
• Two worked cases in the package: a 10-page QBR with a revenue-bridge chart and a 1-page board update, with exact commands.
• Bonus: 3 executive decision-framework prompts.

Read before you buy

• Requires Node 18+ and Python 3.9+. Step 0 of INSTALL.md installs Playwright + Chromium (~82 MB, one-time) and python-pptx. Rendering is core: skipping it fails with Cannot find package 'playwright'. Offline machines cannot render.
• Verified on macOS arm64. Windows and Linux use the same commands but are not re-tested on this build.
• The density gate measures coverage, not font size - keep body copy at 16px or larger. Missing fonts fall back silently; pin a system font or install your brand font.
