Highlights

Live Preview — direct on-canvas editing (no AI round-trip)

The live preview editor gains a full direct-edit surface, so layout nudges no longer need an AI round-trip:

• Object inspector — select any element to edit geometry, safe text content, and raw SVG attributes (fill / stroke / opacity / font-size …). Group and multi-select batch editing supported.
• Drag to move — press-drag a selected element to reposition it; the whole selection moves together under multi-select, mapped through each element's own transform so moves track the cursor at any zoom.
• Arrow-key nudge — ↑ ↓ ← → moves the selection 1px, Shift + arrow 10px.
• Overlap picker — right-click lists every selectable element under the pointer, so stacked shapes can be reached without blind cycling.
• Undo + coalescing — Ctrl+Z / Undo drops the last staged edit; consecutive edits to the same field collapse into one undo step. Staged edits preview live and write to disk only on Apply changes, with an unsaved-work guard before you lose them.

Edits persist through the export pipeline — moved text frames, promoted multi-line tspans, and repositioned icons all reproduce in the PPTX. (workflows/live-preview.md)

LaTeX formula rendering

• New latex_render.py renders LaTeX math to images from a Strategist-locked manifest, with a 4-provider fallback chain (CodeCogs / QuickLaTeX / mathpad / Wikimedia). (scripts/latex_render.py)
• Strategist writes the formula manifest after the typography confirmation; --dry-run validates without rendering.

Converter & export fixes

• Text gradient fills are now preserved on the PPTX → SVG path.
• Pure-translate transforms on text are absorbed into the text frame position instead of being silently dropped.
• Notes slides — dropped a dangling notesMaster relationship and added a package-rels guard, fixing PowerPoint repair prompts on decks with speaker notes.
• PDF source — tighter vector-figure crops.
• EPUB source — gracefully handles broken manifests.

New example decks

• Attention Is All You Need — narrated deck, now the primary download on the README.
• LoRA (Hu et al., 2021).

AI image & Strategist refinements

• text_policy reworked into a two-layer ownership model with per-row judgment (page-level chrome always SVG-owned); subject-domain prompt-depth guidance added.
• AI-image prompt guidance — dropped stale "CJK fails / English-only" capability claims; SVG-overlay reservation scoped to hero_page only; architecture / schematic examples added to §5.3.

Config & infrastructure

• .env lookup order now includes the skill directory (Codex / Cursor loads).
• Default projects/ directory anchored to the current working directory.
• Image generation avoids the OpenAI SDK transport (fixes some proxy setups).
• Resolved a marketplace manifest conflict from a duplicate skills spec.

Docs

• README — new Getting Started guide, slimmed hero, stance note on the Python + agents shape.
• Roadmap opens an "Under consideration" section (LaTeX math was the first entry — now shipped).

Skill-only package — ppt-master-skill-v2.9.0.zip below loads just skills/ppt-master/ as an AI agent skill (Codex / Cursor / non-Claude-Code). The full repository — including the examples/ decks the AI reads to learn conventions — remains the primary form; clone or download the source for that.
