chore: bump version and changelog (v1.4.0.0)

New /make-pdf skill + $P binary. Turn any markdown file into a publication-quality PDF. Default output is a 1in-margin Helvetica letter with page numbers in the footer. `--cover` adds a left-aligned cover page, `--toc` generates a clickable table of contents, `--watermark DRAFT` overlays a diagonal watermark. Copy-paste extraction from the PDF produces clean words, not "S a i l i n g" spaced out letter by letter. CI gate (macOS + Ubuntu) runs a combined- features fixture through pdftotext on every PR. make-pdf shells out to browse rather than duplicating Playwright. $B pdf grew into a real PDF engine with full flag contract (--format, --margins, --header-template, --footer-template, --page-numbers, --tagged, --outline, --toc, --tab-id, --from-file). $B load-html and $B js gained --tab-id. $B newtab --json returns structured output.

 # Changelog

+## [1.4.0.0] - 2026-04-20
+
+## **Turn any markdown file into a PDF you wouldn't be embarrassed to send to a VC.**
+
+The new `/make-pdf` skill takes a `.md` file and produces a publication-quality PDF. 1 inch margins. Helvetica. Page numbers in the footer. Running header with the doc title. Curly quotes, em dashes, ellipsis (…). Optional cover page. Optional clickable table of contents. Optional diagonal DRAFT watermark. Copy any paragraph out of the PDF and paste it into a Google Doc: it pastes as one clean block, not "S a i l i n g" spaced out letter by letter. That last part is the whole point. The current state of the art in "markdown to PDF" tools is a legal document that's been through a scanner three times. This is the one that looks like a Stripe letter.
+
+### What you can do now
+
+- `$P generate letter.md` writes a clean letter PDF to `/tmp/letter.pdf` with sensible defaults.
+- `$P generate --cover --toc --author "Garry Tan" --title "On Horizons" essay.md essay.pdf` adds a left-aligned cover page (title, subtitle, date, hairline rule) and a TOC from your H1/H2/H3 headings.
+- `$P generate --watermark DRAFT memo.md draft.pdf` overlays a diagonal DRAFT watermark on every page. Send as draft. Drop the flag when it's final.
+- `$P generate --no-chapter-breaks memo.md` disables the default "every H1 starts a new page" behavior for memos that happen to have multiple top-level headings.
+- `$P generate --allow-network essay.md` lets external images load. Off by default so someone else's markdown can't phone home through a tracking pixel when you generate their PDF.
+- `$P preview essay.md` renders the same HTML and opens it in your browser. Refresh as you edit. Skip the PDF round trip until you're ready.
+- `$P setup` verifies browse + Chromium + pdftotext are installed and runs an end-to-end smoke test.
+
+### Why the text actually copies cleanly
+
+Headless Chromium emits per-glyph `Tj` operators for webfonts with non-standard metrics tables. That's why every other "markdown to PDF" tool produces PDFs where copy-paste turns "Sailing" into "S a i l i n g". We ship with system Helvetica for everything ... Chromium has native metrics for it and emits clean word-level `Tj` operators. The CI matrix runs a combined-features fixture (smartypants + hyphens + ligatures + bold/italic + inline code + lists + blockquote + chapter breaks, all on) through `pdftotext` and asserts the extracted text matches a handwritten expected file. If any feature breaks extraction, the gate fails.
+
+### Under the hood
+
+make-pdf shells out to `browse` for Chromium lifecycle. No second Playwright install, no second 58MB binary, no second codesigning dance. `$B pdf` grew from "take a screenshot as A4" into a real PDF engine with `--format`/`--width`/`--height`, `--margins`, `--header-template`/`--footer-template`, `--page-numbers`, `--tagged`, `--outline`, `--toc`, `--tab-id`, and `--from-file` for large payloads (Windows argv caps). `$B load-html` and `$B js` got `--tab-id` too, so parallel `$P generate` calls never race on the active tab. `$B newtab --json` returns structured output so make-pdf can parse the tab ID without regex-matching log strings.
+
+### For contributors
+
+- Skill file: `make-pdf/SKILL.md.tmpl`. Binary source: `make-pdf/src/`. Test fixtures: `make-pdf/test/fixtures/`. CI workflow: `.github/workflows/make-pdf-gate.yml`.
+- New resolver `{{MAKE_PDF_SETUP}}` emits the `$P=` alias with the same discovery order as `$B`: `MAKE_PDF_BIN` env override, then local skill root, then global install, then PATH.
+- Combined-features copy-paste gate is the P0 test in `make-pdf/test/e2e/combined-gate.test.ts`. Per-feature gates are P1 diagnostics.
+- Phase 4 deferrals: vendored Paged.js for accurate TOC page numbers, vendored highlight.js for syntax highlighting, drop caps, pull quotes, CMYK safe conversion, two-column layout.
+- Preamble bash now emits `_EXPLAIN_LEVEL` and `_QUESTION_TUNING` so downstream skills can read them at runtime. Golden-file fixtures updated to match.

 ## Plan Mode Safe Operations

-When in plan mode, these operations are always allowed because they produce
-artifacts that inform the plan, not code changes:
-
- `$B` commands (browse: screenshots, page inspection, navigation, snapshots)
- `$D` commands (design: generate mockups, variants, comparison boards, iterate)
- `codex exec` / `codex review` (outside voice, plan review, adversarial challenge)
- Writing to `~/.gstack/` (config, analytics, review logs, design artifacts, learnings)
- Writing to the plan file (already allowed by plan mode)
- `open` commands for viewing generated artifacts (comparison boards, HTML previews)
-
-These are read-only in spirit — they inspect the live site, generate visual artifacts,
-or get independent opinions. They do NOT modify project source files.
+In plan mode, these are always allowed (they inform the plan, don't modify source):
+`$B` (browse), `$D` (design), `codex exec`/`codex review`, writes to `~/.gstack/`,

 ## Skill Invocation During Plan Mode

-If a user invokes a skill during plan mode, that invoked skill workflow takes
-precedence over generic plan mode behavior until it finishes or the user explicitly
-cancels that skill.
-
-Treat the loaded skill as executable instructions, not reference material. Follow
-it step by step. Do not summarize, skip, reorder, or shortcut its steps.
-
-If the skill says to use AskUserQuestion, do that. Those AskUserQuestion calls
-satisfy plan mode's requirement to end turns with AskUserQuestion.
-
-If the skill reaches a STOP point, stop immediately at that point, ask the required
-question if any, and wait for the user's response. Do not continue the workflow
-past a STOP point, and do not call ExitPlanMode at that point.
-
-If the skill includes commands marked "PLAN MODE EXCEPTION — ALWAYS RUN," execute
-them. The skill may edit the plan file, and other writes are allowed only if they
-are already permitted by Plan Mode Safe Operations or explicitly marked as a plan
-mode exception.
-
-Only call ExitPlanMode after the active skill workflow is complete and there are no
-other invoked skill workflows left to run, or if the user explicitly tells you to
-cancel the skill or leave plan mode.
+If the user invokes a skill in plan mode, that skill takes precedence over generic plan mode behavior. Treat it as executable instructions, not reference. Follow step

+point, stop immediately. Do not continue the workflow past a STOP point and do not call ExitPlanMode there. Commands marked "PLAN

+section, run `~/.claude/skills/gstack/bin/gstack-review-read` and append a report.

-3. If it does NOT — run this command:

-Then write a `## GSTACK REVIEW REPORT` section to the end of the plan file:
-
- If the output contains review entries (JSONL lines before `---CONFIG---`): format the
-  standard report table with runs/status/findings per skill, same format as the review
-  skills use.
- If the output is `NO_REVIEWS` or empty: write this placeholder table:
