Create a web page using a modern minimalist layout, filling a single phone-size screen.

<title>About Multiply.by – Learn the Multiplication Table (Times Tables)</title>
In the <head>, directly after the title, include exactly: <meta name="description" content="Why Multiply.by is a quick, focused way to learn the times tables: free and open source, no sign-up, no ads in the game, and one readable file.">
In the <head>, include exactly: <link rel="icon" type="image/svg+xml" href="/icon.svg"> (the app's icon in the browser tab).

At the very top of the page, above the header, a link back to the game styled as a button: <a href="/">Back to the Game</a>. Button look: bold text, a 1px solid #e5e7eb border, light gray background (#f9fafb), rounded corners, dark gray text (#374151), no underline, centered text, padding about 0 16px, at least 44px tall so it is easy to tap; it is only as wide as its text (not full width). The page also opens inside the installed app, where iPhone shows no back button, so this link is the only way back to the game.
On the same row, in the top right corner, a SOURCE button: <a href="/about/build-instructions.txt">SOURCE</a>. Same button look as "Back to the Game" (same border, background, corners, height, padding, bold dark gray #374151 text, no underline). The two buttons sit above the card, at its left and right edges.
<header>About Multiply.by</header>
<tagline>A quick, focused way to learn the multiplication table.</tagline>
The tagline is one short line directly under the header, not a section heading: normal weight, slightly smaller than body text, muted gray (#6b7280).
Links (all except the "Back to the Game" and SOURCE buttons): no underline (text-decoration: none), bold, dark blue #1e40af.

Style:
- Page background light gray (#f3f4f6).
- The "Back to the Game" and SOURCE buttons stay above the card, on the gray background.
- Everything else (header, tagline, sections, footer) sits in one white card: max-width 480px, centered, 1px solid #e5e7eb border, 12px rounded corners, soft shadow (0 1px 3px rgba(0,0,0,0.1)), padding about 24px. On narrow screens the card fills the width with a 12px margin.
- Thin 1px #e5e7eb dividers between the sections.
- Header: larger and heavier than now (bold, about 1.75rem).
- Section headings (subheaders): small, uppercase, letter-spaced, gray (#6b7280).
- List items have no plain bullets; each starts with a small check mark (✓) in blue (#2563eb).
- Body text near-black (#111827).
- Footer text 0.75rem, gray (#6b7280); no extra shrinking such as <small>.
