-- [x] Button platform chrome — the filled variants' 1px border gated behind
-      `Theme::borders.buttons` (Windows / KDE keep it, macOS / GNOME paint
-      fills, ghost stays borderless); icon-bearing buttons pad with
-      `dense_padding_x` instead of `padding_x`
+- [x] Button platform chrome — every variant always paints the hairline
+      border, sized outside the stated control height (`BORDER_WIDTH`); where
+      the platform paints no border (`Theme::borders.buttons`, ghost) the
+      border takes the fill's color and disappears, so sizes match across
+      platforms; icon-bearing buttons pad with `dense_padding_x` instead of
+      `padding_x`
 - [x] Button loading state — `.loading(true)` shows the spinner in place of
       the icon and suppresses activation; Spinner gained a `.color` override
       for accent-filled surfaces
+- [x] Input platform chrome — the field always paints the hairline border,
+      sized outside the stated field height; where the platform paints no
+      border (`Theme::borders.fields`) it takes the field's fill; focus
+      recolors the border on Windows / KDE and paints the accent ring on
+      macOS / GNOME via `Theme::borders.focus_ring`; the shared `focus_ring`
+      band paints at half ink (every focusable control picks it up)
+- [x] Input prefix / suffix — elements docked inside the field's edges,
+      typically small ghost buttons; a docked click activates the control
+      without reaching the field's caret handler, and the text region shrinks
+      to make room
