 - **2026-04-22 global dual-mascot pattern (Claude top-left, Gemini top-right)**: the deck now renders two persistent corner mascots on every slide via a pair of fixed-position `<div class="header-logo">` elements just before the `.navigation` block. CSS: `.header-logo` is `position: fixed; top: 20px; left: 40px; width: 100px; height: 65px; z-index: 50` (Claude, top-left). `.header-logo.right` adds `left: auto; right: 40px` to flip it to top-right (Gemini). Assets: `../../!/claude-jumping.svg` and `../../!/gemini-jumping.svg` — both verified present at repo root `!/`. The Gemini jumping mascot pairs with the Claude one for the GDG dual-CLI deck. Per-slide mascot `<img>` tags that were hardcoded on slide 1 (with `position: absolute`) are now deleted — use global divs only. The `style="position: relative;"` that was on the slide 1 wrapper was removed because it only existed to anchor those absolute-positioned per-slide mascots. **z-index safety**: mascots at z-index 50 sit below `.journey-bar` (99) and `.navigation` / `.progress` (100) — no overlap. The journey bar is at `right: 62px; top: 95px`, which is far enough below `top: 20px` that the right mascot and the bar track do not visually collide. **Rule**: for any GDG dual-CLI deck, always use this two-div global pattern rather than per-slide mascots — it guarantees consistent placement across all 40 slides without per-slide maintenance.
 - **2026-04-24 slide 6 jargon-cloud tier reshuffle**: `vibe coding` demoted from hero-blue to small-orange (top: 91% / left: 22%); `harness` and `compaction` promoted from purple to hero-blue (kept positions, upgraded padding/font/shadow); `context window` added as new hero-blue pill (top: 32% / left: 5%); `context engineering` deleted (pill + legend row both removed). Legend rebalanced: left column = 8 blue + 2 purple (10 rows), right column = 4 green + 5 orange (9 rows) — slight asymmetry because green dropped from 5 to 4 after context-engineering removal; acceptable. Key verification method: Python script extracting all `background: #HEX` pill texts and all `color: #HEX; font-weight: 700` legend texts per color — confirmed exact match for all 4 tiers. Total slides and data-level dividers unchanged (51 / 21,27,33,38,44,47).
 - **2026-04-24 restore-original + keep-new insert at slot 9 (50 → 51 slides)**: the "Can answer / Can't answer" grid (commit `61a847c`) was restored at slot 9 and the Stochastic Parrots slide (authored in `fa1b499`) was shifted to slot 10. Recovery method: `git show 61a847c:...index.html | sed -n 'LINE,LINEp'` to extract the exact pre-edit markup, then Edit tool to insert it before the current slot-9 comment block, then a Python sentinel-replacement script to renumber old slides 10-50 → 11-51. The sentinel approach is mandatory here because Python `str.replace` applies all substitutions, so descending-order alone is insufficient for a multi-value renumber (unlike sed's single-expression-per-call mode). No `goToSlide` hardcoded calls exist in this deck — only the function definition — so no TOC update was needed. `totalSlides` is DOM-computed, no hardcoded bump. New section-divider positions: **Agents=21, Skills=27, Context=33, CLAUDE.md=38, Commands=44, Workflow=47**. Total slides: **51**. git ref for the original slide 9 content: `61a847c`.
+- **2026-04-24 insert 4 CLAUDE.md teaching slides at positions 33-36 (59 → 63 slides)**: new slides inserted between slide 32 (CLAUDE.md concept-intro section divider) and old slide 33 (Skills section divider). All four carry `data-level="claude-md"` so the level-badge fires at slide 33 and stays on through the CLAUDE.md arc. New slides: 33 ("Create your first CLAUDE.md — `/init`", mirrors slide-24 agent-creation template with purple accent `#9c27b0`), 34 (screenshot `../assets/concepts/claudemd/claudemd.png`), 35 (tips image `../assets/concepts/claudemd/claudemd-tips.png`), 36 (problem image `../assets/concepts/claudemd/claudemd-problem.png`). All images verified present before writing. Old slides 33-59 shifted to 37-63 using Python sentinel replacement (second-occurrence targeting for 33-36, single-occurrence for 37-59). No `goToSlide` hardcoded calls exist — no TOC update needed. Final section-divider positions: **Agents=23, Skills=39, Context=45, CLAUDE.md=33+50, Commands=56, Workflow=59**. Total slides: **63**. **Redundancy flag on slide 50**: old CLAUDE.md section opener "Topic 4 — The Reporter's Pocket Rulebook" (`data-level="claude-md"`, `section-slide` class) at slide 50 is now downstream of the new teaching slides 33-36 which already fire `→ CLAUDE.md` at slide 33. The badge will NOT re-fire at 50 (same level = no change). The slide is visually a full-screen section divider with a weather-reporter metaphor description — it still serves as a breathing-space divider between the "how to use CLAUDE.md" block (33-36) and the "deep dive" block (51-55). Recommended: keep for now, flag for user to decide whether to promote it into the new cluster or demote to a regular slide. **Dual-CLAUDE.md level pattern**: when a topic has a concept-intro (slide 32 section divider) plus early how-to slides (33-36) plus a deeper narrative arc (50-55), the level fires twice in the deck — at 33 (shallow intro cluster) and again via the section opener at 50 (deep dive). This is working-as-designed for the journey bar. **Double-sentinel rule for same-number collisions**: when inserting N new slides at position P and those new slides use data-slide values P through P+N-1, the old slides at those same values become "second occurrences." Replace second occurrences (not first) with sentinels before resolving — Python `str.find(target, first_pos+1)` pattern is the correct approach.
 - **2026-04-24 three concept-intro slides inserted at 27-29 (51 → 54 slides)**: new slides 27 (CLAUDE.md), 28 (Skills), 29 (Context) inserted immediately before the old Skills section opener (now at 30). All three use `class="slide section-slide"` with NO `data-level` — they are concept intros, not arc-level openers, so the journey bar should not advance on them. Pill choices: CLAUDE.md uses `CLAUDE.md` as the filename (monospace yellow pill — no slash command exists); Skills uses `.claude/skills/` as the filesystem path (no `/skills` slash command exists — verified against CLAUDE.md which shows skills are file-based, not command-invoked); Context uses `/context` — this IS a real Claude Code command (shows current token usage breakdown). Slide 29 (Context) intentionally has NO file-tree because context is a runtime concept, not a filesystem artifact. Renumber method: sentinel technique with 3-phase Python script — (1) replace all `data-slide="27"` through `"51"` with `##SEN27##` through `##SEN51##`, (2) restore the FIRST occurrence of sentinels 27/28/29 (the new slides) back to their correct values using `str.replace(..., 1)`, (3) resolve remaining sentinels N→N+3. Section-divider positions after insert: **Agents=23, Skills=30, Context=36, CLAUDE.md=41, Commands=47, Workflow=50**. Total slides: **54**.
 - **2026-04-24 pillar-footer strip added to slides 23-29**: compact 5-card reference bar added below the viewport fold on slides 23-29. Implementation uses Option A: each slide's existing content is wrapped in a `.slide-viewport-content` div (`min-height: 100vh; display: flex; flex-direction: column; align-items: center; justify-content: center; width: 100%`) and a `.pillar-footer` sibling div (flex row, `gap: 10px; justify-content: center; max-width: 1000px; margin: 60px auto 40px auto`) is appended after the wrapper. Each footer contains 5 `.pillar-mini-card` divs (flex row, `padding: 10px 14px`, `border-radius: 8px`, `box-shadow: 0 2px 6px rgba(0,0,0,0.08)`) with emoji + title only — no body text. Active-pillar highlighting is implemented: the current topic's card has `border-left: 5px solid <color>` and no `.inactive` class; the other four have `border-left: 3px solid <color>` and class `pillar-mini-card inactive` (`opacity: 0.45`). Active assignments: slides 23-26 → Agents, slide 27 → CLAUDE.md, slide 28 → Skills, slide 29 → Context. Section-dividers (slides 23, 27, 28, 29) kept `justify-content: center` for `.slide-viewport-content`; content slides (24, 25, 26) use `justify-content: flex-start; padding-top: 60px` on `.slide-viewport-content` to keep the h1 near top. Scroll reset (`window.scrollTo(0, 0)` in `showSlide()`) was already present from a prior session — no JS change needed. The 5 pillar colors exactly match slide 14's card borders: Agents `#009688`, Skills `#4caf50`, Workflows `#ef6c00`, CLAUDE.md `#9c27b0`, Context `#3f51b5`. Total slide count (54) and all data-level positions unchanged. **At 1024px width**: each mini-card is `~18%` of 1000px = ~180px. With `flex: 1` and `min-width: 0`, cards compress gracefully — the 12-char "CLAUDE.md" title at `font-size: 0.82rem` is ~96px, well within 180px. No wrapping expected at standard presentation viewports.
 - **2026-04-24 content-slide heading centering fix (slides 24/25/26)**: the `.slide-viewport-content` wrapper (`min-height: 100vh; display: flex; align-items: center`) was centering headings vertically even with `justify-content: flex-start` inline override — `align-items: center` acts on the cross-axis (horizontal in a column flex), but the real problem is that the full-viewport-height flex container pushes content away from the top edge. Fix: removed `.slide-viewport-content` entirely from slides 24 and 26 (plain content slides with substantial content), letting them flow exactly like slide 22 — h1 at top, content below, no wrapper at all. Slide 25 (Demo — nearly empty body) uses a plain `<div style="min-height: calc(100vh - 120px);">` spacer wrapping only the h1, so the footer is pushed below the fold without any flex centering. Section-divider slides 23/27/28/29 keep their `.slide-viewport-content` wrapper unchanged — they are supposed to be viewport-centered. **Rule**: for content slides with a pillar-footer, do NOT wrap in `.slide-viewport-content`. Use a bare spacer div only on near-empty content slides (less than ~3 elements of body content) to push the footer below the fold.
 - **2026-04-24 image-only tips slides inserted at 31 and 32 (57 → 59 slides)**: two new slides inserted after slide 29 (the last agents-section content slide) before slide 30 (the CLAUDE.md section intro). Both slides are plain content slides with `data-level="agents"` so the journey bar stays on the agents level without re-firing. Layout: bare `<h1>` (no wrapper) + flex-centered `<div style="min-height: calc(100vh - 200px);">` containing the `<img>`. The `-200px` calculation (h1 ~100px + pillar-footer ~100px gap) matches slide 26's pattern for full-bleed image slides. Pillar-footer is included with Agents as the active card (matching the active pattern on slides 26-29). Renumber method: Python sentinel script — each `data-slide="N"` for N=31-57 replaced via `##SENTINELN##` intermediates, then resolved to N+2. No `goToSlide` hardcoded calls exist in this deck; `totalSlides` is DOM-computed. Section-divider positions after insertion: **agents=23 (unchanged), skills=35, context=41, claude-md=46, commands=52, workflow=55**. Total slides: **59**. Images at `../assets/concepts/agents/agent-tips-1.png` and `agent-tips-2.png` — both verified present before insertion.
+- **2026-04-24 Skills emoji updated + 2 new slides inserted at 38-39 (63 → 65 slides)**: Edit 1 — slide 37's h1 emoji changed from `&#x1F393;` (graduation cap) to `&#x1F3AF;` (target) to match the Skills pillar-footer card emoji established on slide 14 and used across all 12 pillar footers. Edit 2 — new slide 38 ("Create your first skill", `data-level="skills"`) inserted with a `.two-col` layout: two `.col-card` divs (both green `#4caf50` border-left) for Method 1 (write by prompting) and Method 2 (use Anthropic's `skill-creator`), followed by an inline amber warning box (`background: #fff3e0; border-left: 4px solid #ff9800`) flagging the wrong-structure gotcha of Method 1. Edit 3 — new slide 39 ("Skill config fields with frontmatter", `data-level="skills"`) mirrors slide 29's agent field-table pattern exactly: 8 field rows using `.field-row` / `.field-name` / `.field-desc` / `.field-enforced` / `.pill-harness` / `.pill-prompt` CSS classes, italic intro sentence, and a centered `.fafafa` footnote callout for `description`. Old slides 38-63 renumbered to 40-65 via Python sentinel replacement (descending-order sentinel phase + resolve phase). **Redundancy flag**: old Skills section opener (was slide 39, now slide 41 — `data-level="skills"`, `section-slide` class, "Topic 2 — What the Weather Reporter Knows") is now downstream of the new teaching slides 38-39 which already fire `→ skills` earlier. Same pattern as the CLAUDE.md dual-fire situation at slides 33 and 52. Recommended: keep slide 41 as a breathing-space divider into the weather-reporter narrative arc; the journey bar will not re-fire (same level). Final section-divider positions: **Agents=23, Skills=38 (first skills data-level), Context=47, CLAUDE.md=52, Commands=58, Workflow=61**. Total slides: **65**.
