A terminal slide can't scroll, so a long bibliography ran off the bottom. bib.Process now emits one '## References' slide plus as many '## References (cont.)' slides as needed, at most 6 entries each.

A slide carrying '<!-- run -->' executes its code blocks automatically when it is shown and displays only their output -- the source is stripped before rendering. Built for terminal plots (UnicodePlots.jl): navigating to the slide draws the graph with no keystroke. - autoRun() fires executeCodeCmd on slide entry (batched with the image load), or restores a per-page cached result on revisit so the slide doesn't re-run and flicker. - code.Warm() kicks off a throwaway 'using UnicodePlots' at load so the first auto-run slide doesn't stall on Julia's precompile. - cached execution temp dirs are cleaned on quit.

Process now numbers cited entries 1..N in alphabetical order of the reference (first author's family name, then year, then title; entries with no author sort by title) and lists the References slide in that order -- IEEE-numbered with alphabetical ordering. In-text [n] markers therefore need not appear in ascending order. Replaces first-appearance numbering.

A 'theme: theme.json' in the frontmatter now loads from the presentation file's folder, like bibliography and images already do, instead of the process's working directory -- so 'slides sub/dir/deck.md' finds sub/dir/theme.json. Builtin keywords (ascii/light/dark/notty), URLs and absolute paths are unchanged.

computeMediaBudget now renders the slide's text alone -- images and $$ blocks removed, captions kept -- and measures how many rows it actually occupies at the current width, then splits the remaining height across the media items. Replaces the fixed reservedRows guess, which was too small when a slide carried a paragraph or a bullet list around the figure, so the figure overran the text beneath it (or pushed it off the bottom). Cached in Model.mediaRows and refreshed on every page change and resize, so the fit re-measures as Kitty's font size changes.

A slide with '<!-- center -->' on its own line gets every text line horizontally centered within the content width after rendering; Kitty graphics placeholders keep their existing PadLeft centering. The marker is stripped before glamour sees it, like <!-- pause -->. For closer / section / figure-caption slides.

mediaBudget() splits a slide's usable height across every media item it carries (each image and each $$…$$ block is a real graphic), so slides with several stacked figures/equations no longer overflow the viewport and get their last figure clipped off the bottom. Recomputed on every WindowSizeMsg, so it tracks Kitty font-size / zoom live. Replaces the fixed reservedRows=10 guess. latex.Warm() pre-renders every unique display-math block in the deck concurrently in the background from Load(), so navigating to a slide with equations is a cache hit instead of tectonic's cold start one block at a time. loadImagesCmd rasterizes a slide's blocks in parallel too. dpi 200 (down from 300) roughly halves Ghostscript's work; the PNG is downscaled to a few cells regardless, with TextAlphaBits=4 keeping edges smooth.

Every example is now its own self-contained folder (matching the arquimedes/matlab-laser-mic pattern that was already here), instead of a flat mix of loose .md files and asset folders. Updates the few repo-root-relative paths that pointed at the old flat layout: Makefile, docs/development, custom_theme.md's theme path, and preprocess.md's import path. arquimedes/ and matlab-laser-mic/ are no longer gitignored -- they're real presentations built with this fork, worth keeping versioned instead of local-only.

UnicodePlots (and any other code block's plain stdout) now centers the same way image-based plots already do via their own PadLeft, instead of hugging the left edge while GR/CairoMakie output sits in the middle. Also adds a Julia example that saves an animated GIF from a ctrl+e block -- confirms the existing GIF cache path (Fase 7) already applies to execution-produced images too, no code change needed there.
