+# Mobile readability fixes — `index.html`
+
+Base: commit `3dcd822` (`bitcoinafterlife/bal-welist-website`, `main`).
+
+**Scope:** header, filter bar and server list only. CSS-only — the JavaScript is
+byte-for-byte unchanged. Desktop rendering is unaffected: every change sits
+inside a `@media (max-width: ...)` block, except one line on `body` (item 7).
+
+The "Add your Will Executor" panel, the invoice and the QR code were left
+untouched on purpose, since payments are expected to be made from a desktop
+browser.
+
+---
+
+## 1. Chain selector overflowed the viewport
+
+**Before:** `.seg` was an `inline-flex` row of four buttons (Bitcoin, Testnet,
+Testnet4, Regtest) with no wrapping — roughly 340px wide. On a 360–390px phone,
+minus page padding, it pushed past the right edge and made the whole page scroll
+horizontally.
+
+**After:** below 600px the selector becomes a full-width 2×2 grid. Inner
+dividers are recalculated with `:nth-child` so the borders stay correct in the
+new arrangement.
+
+## 2. Touch targets too small
+
+Chain buttons were ~33px tall. Raised to `min-height: 44px` (the standard
+minimum for a finger), applied to the chain buttons, the Tor toggle row and the
+JSON link.
+
+## 3. Nested scrolling in the server list
+
+**Before:** `.mobile-list` carried `max-height: 350px; overflow: auto`, so on a
+phone the list was a small window scrolling inside a page that also scrolls —
+the two gestures fight each other.
+
+**After:** the height cap is removed below 860px; the list flows with the page.
+The desktop table (`.table-card`) keeps its 350px cap unchanged.
+
+## 4. Long URLs broke out of the cards
+
+Server URLs contain no spaces, so the browser cannot break them and they
+overflowed the card. Added `overflow-wrap: anywhere`, plus `min-width: 0` on the
+flex parent — without it a flex child defaults to `min-width: auto` and refuses
+to shrink below its content width.
+
+The JS truncation at 40 characters is unchanged.
+
+## 5. Uneven card grid
+
+The five fields (Score, Wins, Fee, Version, Height) sat in two fixed columns,
+leaving Height alone on a half-empty row. Switched to
+`repeat(auto-fit, minmax(84px, 1fr))`, which fits as many columns as the width
+allows.
+
+## 6. iOS auto-zoom on the search field
+
+iOS Safari zooms the entire page when a focused input has a font size below
+16px, and the user then has to pinch back out. The filter field is raised to
+16px below 600px and made full width.
+
+## 7. Text inflation in landscape
+
+Added `-webkit-text-size-adjust: 100%` to `body`. iOS enlarges font sizes when a
+phone is rotated to landscape, which distorted the header and the cards. This is
+the only change outside a media query; it has no effect on desktop browsers.
+
+## 8. Tighter spacing below 480px
+
+New breakpoint reducing padding and type size where space is scarce:
+
+| Element | Before | After |
+| --- | --- | --- |
+| `.wrap` side padding | 20px | 14px (+12px usable width per row) |
+| `header.hero` padding | 48px 0 28px | 28px 0 20px |
+| `.brand h1` | 24px | 20px |
+| Logo mark | 46px | 40px |
+| `.stat .n` | 26px | 22px |
+| `.intro-card` padding | 28px 32px | 20px 18px |
+| `.info-block` padding | 22px 24px | 18px 16px |
+| `.srv` padding | 16px | 14px |
+| Footer | space-between, wrapping | single column |

+## Verification performed
+
+- CSS braces balanced (148 open / 148 close).
+- All 32 element IDs referenced by the JavaScript still present in the markup.
+- Tag balance checked for `div`, `section`, `header`, `footer`, `main`, `table`,
+  `style`, `script`.
+- Media queries present in order: 860px, 600px, 480px, `prefers-reduced-motion`.
+
+## Not yet verified
+
+Rendering was not tested on a physical device. Worth a quick check on one iPhone
+and one Android phone before merging, in particular the 2×2 chain selector at
+320px width (iPhone SE, the narrowest screen still in common use).
