// RECIPE 6: IEEE CONFERENCE (IEEEtran)
// ════════════════════════════════════════════════════════════════════════
/// <summary>
/// Recipe: IEEE Conference Paper (IEEEtran.cls v1.8b)
/// Source: IEEEtran.cls v1.8b — the standard LaTeX class for IEEE transactions
/// and conference proceedings.
///
/// Feel: Dense, formal, information-rich two-column layout.
/// Best for: IEEE conference submissions, transactions papers, technical reports
/// following IEEE style.
///
/// Design rationale (all values from IEEEtran.cls source):
/// - US Letter, narrow margins (0.625in L/R): maximizes text area for the
/// two-column layout. IEEE papers prioritize information density.
/// - Two columns with 0.25in (360 DXA) gutter: standard IEEE column separation.
/// Narrow gutter is feasible because the small font creates short line lengths.
/// - 10pt Times New Roman body (sz=20): IEEE's standard body size. TNR is the
/// required typeface. 10pt in two columns yields ~40 characters per line —
/// optimal for rapid technical reading.
/// - 24pt title, centered, NOT bold (sz=48): IEEEtran titles are large but
/// use regular weight. The size alone provides hierarchy.
/// - Section headings (H1): 10pt small caps, centered, Roman numeral prefix
/// convention (sz=20). Small caps at body size creates subtle hierarchy
/// without disrupting the dense layout.
/// - Subsection headings (H2): 10pt italic, flush left (sz=20). Italic at
/// body size is the minimal viable distinction from body text.
/// - Single spacing (line=240): mandatory for IEEE camera-ready format.
/// - First-line indent 0.125in (180 DXA): very small indent suits the narrow
/// column width.
/// - 0pt paragraph spacing: IEEE uses no inter-paragraph space; the first-line
/// indent is the sole paragraph separator.
/// - Captions: 8pt (sz=16) — subordinate to body, centered under figures/tables.
/// </summary>

// RECIPE 7: ACM CONFERENCE (acmart)
// ════════════════════════════════════════════════════════════════════════
/// <summary>
/// Recipe: ACM Conference Paper (acmart.cls v2.x, ACM Author Guide)
/// Source: acmart.cls v2.x — the consolidated ACM master article template,
/// and the ACM Author Guide for typographic specifications.
///
/// Feel: Clean, structured, slightly more open than IEEE.
/// Best for: ACM conference proceedings (SIGCHI, SIGMOD, SIGGRAPH, etc.),
/// ACM journal submissions.
///
/// Design rationale (all values from acmart.cls and ACM Author Guide):
/// - US Letter, 1.25in top/bottom, 0.75in L/R: more generous vertical margins
/// than IEEE, giving a less cramped appearance.
/// - Two columns with 0.33in (480 DXA) gutter: slightly wider than IEEE's
/// 0.25in, providing better visual separation between columns.
/// - 9pt Times New Roman body (sz=18): ACM's standard body size. The original
/// acmart uses Linux Libertine, but TNR is the accessible fallback specified
/// in the ACM Author Guide for systems without Libertine.
/// - 14.4pt bold title, flush left (sz=29): ACM titles are bold and left-aligned,
/// unlike IEEE's centered unbolded titles. The 14.4pt size (1.6x body) creates
/// strong but not overwhelming hierarchy.
/// - H1: 10pt bold ALL CAPS, flush left, arabic numbered (sz=20). ALL CAPS at
/// body size with bold creates definitive section breaks.
/// - H2: 10pt bold title case, flush left (sz=20). Bold without caps is the
/// minimal step down from H1.
/// - H3: 10pt bold italic, flush left (sz=20). Adding italic distinguishes
/// from H2 while maintaining the same weight.
/// - Single spacing: required for ACM camera-ready format.
/// - First-line indent ~10pt (200 DXA): slightly larger than IEEE's 0.125in,
/// matching ACM's convention of a roughly 1em indent at 9pt.
/// - Captions: 8pt (sz=16) — consistent with ACM figure/table caption style.
/// - References: 7.5pt (sz=15) — ACM uses a smaller font for the bibliography
/// to maximize space for content.

/// - No mandatory heading system. If headings are used, they should be simple and
/// consistent. MLA does not prescribe heading levels like APA does.
/// - Running header: Author's last name and page number, flush right, 0.5 inch from top.
/// - First-page header block: Student's name, instructor's name, course title, and
/// date — upper left, double-spaced, NO extra spacing.
/// - Works Cited: title "Works Cited" centered (not bold), entries have hanging indent
/// of 0.5 inch (first line flush left, subsequent lines indented).
/// - No title page required (unless specifically requested by instructor).
///
/// Design rationale:
/// - MLA's aesthetic is deliberately plain — the writing is the content.
/// - No bold headings, no size variation, no decorative elements.
/// - The only structural markers are centering (title, Works Cited label)
/// and indentation (paragraphs, hanging indent for citations).
/// - This uniformity reflects MLA's roots in literary studies, where the
/// text itself is paramount and formatting should be invisible.

"The concept of the unreliable narrator, first articulated by Wayne C. Booth in "
+ "The Rhetoric of Fiction (1961), provides a foundational framework for understanding "
+ "Humbert's discourse. Booth argues that unreliable narrators are those whose values "

+ "prose, the literary allusions, the self-deprecating wit \u2014 all serve to create what "

+ "themselves sympathizing with a narrator whose actions they would condemn.",
"Normal");

"The structural implications of Humbert's unreliability extend beyond mere "
+ "factual distortion. As Eric Naiman demonstrates, the novel's famous opening "

// EMU (English Metric Unit) is the universal measurement in DrawingML:
// 1 inch = 914400 EMU
// 1 cm = 360000 EMU
// 1 px@96dpi = 9525 EMU (914400 / 96 = 9525)

// Image architecture in OpenXML:
// Paragraph → Run → Drawing → DW.Inline (or DW.Anchor)
// → A.Graphic → A.GraphicData → PIC.Picture
// → PIC.BlipFill → A.Blip (references the image part via r:embed)
// → PIC.ShapeProperties → A.Transform2D → A.Extents (cx, cy)
//
// CRITICAL RULES:
// 1. Extent.Cx/Cy on DW.Inline/DW.Anchor MUST match A.Extents.Cx/Cy
// on PIC.ShapeProperties. Mismatch causes rendering issues.
// 2. Each Drawing element needs a unique DocProperties.Id within the document.
// 3. ImagePart must be added to the PART that references it:
// - MainDocumentPart for images in body
// - HeaderPart for images in headers
// - FooterPart for images in footers
// 4. Blip.Embed contains the relationship ID (rId) linking to the ImagePart.

// ============================================================================
// ListAndNumberingSamples.cs — OpenXML numbering system deep dive
// ============================================================================
// OpenXML list/numbering architecture (3 layers):
//
// 1. AbstractNum — defines the numbering FORMAT (bullet chars, number formats,
// indentation, fonts). Contains Level elements (0-8) for multi-level lists.
//
// 2. NumberingInstance (Num) — a concrete "instance" that references an
// AbstractNum. Multiple paragraphs share the same NumId to form one list.
// LevelOverride on a NumberingInstance can restart numbering.
//
// 3. NumberingProperties on Paragraph — links a paragraph to a NumberingInstance
// via NumId + Level (ilvl). This is what makes a paragraph a list item.
//
// CRITICAL RULES:
// - In the Numbering root element, ALL AbstractNum elements MUST appear
// BEFORE any NumberingInstance (Num) elements. Violating this order causes
// Word to report corruption.
// - LevelText uses %1, %2, %3 etc. as placeholders for the current value
// at each level. %1 = level 0's value, %2 = level 1's value, etc.
// - NumberingSymbolRunProperties (rPr inside Level) sets the font for the
// bullet character or number. Without it, the bullet may render in the
// paragraph's font, which can produce wrong glyphs.
// - IsLegalNumberingStyle on a Level forces "legal" flat numbering
// (e.g., "1.1.1" instead of outline style) regardless of heading level.
//
// Storage: Numbering definitions live in numbering.xml, accessed via
// NumberingDefinitionsPart on the MainDocumentPart.
// ============================================================================
