Compile Deck

Create beautiful Beamer presentations. This skill enforces the Rhetoric of Decks philosophy through concrete, measurable rules — not aspirational guidance.

Step 1: Triage

Before touching anything, answer three questions:

Q1: New deck or editing existing?

• If editing: Read the

  .tex

  file first. Understand its palette, structure, and style before changing anything.
• If new: Proceed to Q2.

Q2: Who is the audience?

1. Academic seminar — sparse, one idea per slide, titles carry the argument
2. Teaching lecture — clarity over compression, repetition OK, progressive revelation
3. Working deck (coauthors) — more detail OK, document choices, preserve uncertainty
4. External non-academic — storytelling, visual impact, minimal jargon

See

domain_patterns.md

Q3: What's the tone?

1. Professional/Academic — use the Warm Professional palette (default) or Academic Muted
2. Colorful/Expressive — create something new each time. See

   palette_reference.md

   for inspiration.

Step 2: The Non-Negotiable Rules

These are not guidelines. They are constraints.

ONE idea per slide

If a slide has two ideas, split it. No exceptions.

Titles are assertions, not labels

• Bad: "Results"
• Good: "Treatment increased distance by 61 miles on average"
• Bad: "Literature Review"
• Good: "Prior work ignores the supply-side margin"

If someone reads only the slide titles in sequence, they should understand the entire argument.

Typography minimums

• Body text: 24pt minimum
• Absolute floor (footnotes, source notes): 18pt
• Sans-serif fonts only
• Never justify text — always ragged right

No bullet lists (usually)

Bullets are a confession that you haven't found the structure. Look for:

• A sequence (use a flow diagram)
• A contrast (use two columns)
• A hierarchy (use size/color differentiation)
• A causal chain (use arrows)

Exception: genuinely parallel items (e.g., a list of axioms in a teaching deck).

Charts: one message, direct labels

• Every chart communicates ONE finding
• Title states the finding ("Enrollment doubled after 2015"), not the chart type ("Enrollment Over Time")
• Label data directly on the chart — no legends requiring eye movement
• Remove all chartjunk: gridlines, borders, unnecessary axis marks

White space is confidence, not waste

Empty space on a slide signals that you chose carefully. A full slide signals anxiety.

Zero compile warnings

Not "try to fix." Zero. See the Compile Loop below.

Step 3: The Preamble

For new decks, use this template. It is extracted from real decks that work.

Step 4: Slide Architecture Patterns

Opening slide (first content slide after title)

NOT "Motivation" with bullet points. Instead:

• A surprising fact or statistic (big number, centered)
• A puzzle or unanswered question
• A provocative claim that the deck will support

Transition slides

Use

\transitionslide{Section Title}{Subtitle}

Closing slide

NOT "Questions?" or "Thank you." Instead:

• The ONE sentence the audience should remember tomorrow
• Full-bleed dark background with the takeaway centered

Devil's Advocate slide (academic decks)

Present the strongest objection to your argument, then respond to it. This builds credibility. Format: "A skeptic would say..." followed by your response.

TikZ diagram slides

Read

tikz_rules.md

Critical rule preview: Before placing a label between two nodes, CALCULATE the edge-to-edge gap and compare it to the estimated text width. If the text is wider than the gap minus 0.6cm padding, the label WILL collide. Move it above/below or shorten the text.

Step 5: The Compile Loop

After EVERY edit to a .tex file:

5a: Compile

pdflatex -interaction=nonstopmode [file].tex

5b: Check for fatal errors

grep "^!" [file].log

If any: fix, recompile, repeat.

5c: Check for ALL warnings

grep -cE "Overfull|Underfull" [file].log

This must return 0. For EACH warning:

\adjustbox

@{}

\vspace

\vfill

Even 0.5pt overfull must be fixed. Do NOT proceed until the count is 0.

5d: Check fonts

grep -i "font" [file].log | grep -i "warning"

5e: TikZ verification (Bézier-first workflow)

TikZ errors don't trigger compile warnings. You must catch them yourself. Follow this order — curves first, everything else second:

Pass 1 — Find and fix all Bézier curves:

grep -n "bend" [file].tex

For EACH curved arrow found:

1. Calculate max depth:

   (chord / 2) × tan(bend_angle / 2)

2. Add 0.5cm safety margin
3. Check: is any label within the danger zone? Move it if so.
4. Check: does the curve cross any other arrow? Re-route if so.

Pass 2 — Everything else:

• Gap calculation: for every label between two nodes, is estimated text width < usable gap?
• Arrow labels: does every one have

  above

  ,

  below

  ,

  left

  , or

  right

  ?
• No nodes clipped by slide edges
• All arrows pointing to intended targets

Pass 3 — Open the PDF and visually confirm.

tikz_rules.md

5f: Open the PDF

open [file].pdf

Step 6: The Narrative Arc

Every deck tells a story. The structure depends on context, but the principle is universal:

Act I — Setup: Establish the problem or question. Make the audience feel it. Act II — Development: Present evidence, analysis, investigation. Build the logical case. Act III — Resolution: Deliver the insight. State implications. Give the audience something to do or remember.

Within this arc, apply the Pyramid Principle: lead with the conclusion, then support it. Academic audiences expect this. Do not build suspense — state the finding, then prove it.

For domain-specific structures, see

domain_patterns.md

Step 7: Figure Generation

When a deck needs data visualizations:

1. Write a Python script (

   generate_figures.py

   ) using matplotlib
2. Use the same color palette as the LaTeX deck
3. Save figures as PDF (vector, not raster) to a

   figures/

   subdirectory
4. Every figure: one message, direct labels, title states the finding
5. Match the deck's background color in

   fig.set_facecolor()

6. Save the script alongside the figures — never generate a figure without preserving the code that created it
7. Boundary Rule applies to figures too: When placing

   ax.text()

   near patches (

   FancyBboxPatch

   ,

   Circle

   ,

   Rectangle

   ), compute the patch boundary and verify text has ≥0.4cm clearance. See

   tikz_rules.md

   Pass 4.
8. Anchor-Based Centering Rule: When a container holds multiple text elements (title + math), do NOT use

   va='center'

   for both at symmetric offsets — multi-line text extends further from its anchor than single-line, creating visual asymmetry. Instead, anchor outward from center: upper element uses

   va='bottom'

   at

   center + gap

   , lower uses

   va='top'

   at

   center - gap

   . See

   tikz_rules.md

   Pass 4.
9. Bézier-first for matplotlib arrows: When labeling curved arrows (

   arc3

   ), compute the actual Bézier curve position using the arc3 control point formula (

   cx = mid_x + rad*dy, cy = mid_y - rad*dx

   ), then offset labels perpendicular to the computed curve position. Never guess where curves pass. Use a white-background bbox on labels for readability. See

   tikz_rules.md

   Pass 4 for the full formula and workflow.
