+Title: Prototype dynamic slide-view directives ("reslide")
+Status: in-progress
+Priority: high
+Created: 2025-06-27
+Description: Implement a Sphinx extension allowing reStructuredText documents to
+             be rendered as both linear HTML pages and presentation-style
+             slides.
+
+             The system introduces a non-intrusive layer over standard reST
+             content via three main directives:
+
+             - `.. slide-master::` declares a reusable grid-based layout with
+               named areas.
+             - `.. slide::` marks a logical section as a slide and references a
+               master layout.
+             - `.. slide-slot::` maps specific content blocks into areas defined
+               by the referenced slide master.
+
+             Slides are composed in a single reST file without disrupting HTML
+             output.  During HTML build, a toggle button is injected allowing
+             users to switch between document view and presentation view using
+             JavaScript and CSS.
+
+             Additional features include:
+             - Fallback or fluid "resize to fit" mode for content overflow
+             - Optional pre-build warning system for oversized content
+             - Placeholder wireframes for visualizing grid slots (dev mode)
+             - Semantic rendering to preserve readability in both views
+
+             Parsing relies on the sequential nature of reST processing to
+             segment slide contents without modifying global tree behavior.
+
+             This prototype sets up the basic parsing, node registration, and
+             HTML translator customization. Styling and JavaScript interactivity
+             will be minimal but functional.
