outlay 1.4.0

• outlay/render: htmlToSvg — HTML with inline styles to a finished SVG string in one call, the Satori shape with CSS Grid. Text properties (font-family, font-size, font-weight, line-height, color, text-align) inherit down the tree like CSS; the paint vocabulary is solid backgrounds, border-radius, and border-color (a uniform border paints an inset stroke). htmlToLayout returns the { tree, styles } intermediate for solving or inspecting before painting.
• outlay/svg: renderToSvg, a styled painter over solved layouts — fills, strokes, rounded corners, and line-broken text with per-line textLength and CSS half-leading baselines — and renderDebugSvg, a depth-colored box visualizer with grid-track outlines from a debug trace.
• outlay/font: zero-dependency TTF/OTF metrics — parseFont, wordAdvance, spaceAdvance, and measureText to a measureContent callback. Advances are unshaped (kerning off), verified against Chromium to 0.015px with committed Inter ground truth.
• outlay/text gains breakLines: word-range line breaking that shares measureFromAdvances' LayoutUnit-quantized fit test, so painted lines always match measured layout.
• parseHTML gains an opt-in render mode (second parameter) used by outlay/render: text nodes become block measureContent leaves and inherited text + solid-color paint CSS is collected per node. Without it, behavior is byte-for-byte unchanged — text and paint properties still throw.
• New OG-image demo: a 1200×630 CSS Grid card — non-uniform fr columns, spans, text wrapped at the fr-resolved width — measured from a font file and painted to SVG in ~3ms with no browser.
• Rendering-track v1 limitations are tracked in TODO.md.
