/* ---- Focus: a thin ring, drawn INSIDE the box ----------------------------
   Every pixel of this state stays within the input's own border box. The ring
   is `inset`, so it thickens the existing hairline to a crisp 2px instead of
   painting a second shape around the field, and there is no outer glow and no
   transform. /login used to answer focus with `0 0 22px` of violet bloom, HUD
   corner brackets on the label row and a beam bar under the input, all of which
   spilled past the control and into the card's padding - that is the "it crawls
   out" this replaces. /register, /forgot and /reset had the opposite problem:
   `outline: none` with only a border-colour swap, which is not a focus
   indicator at all on a hairline that light.

   One rule for all four pages on purpose: the same field must not answer focus
   differently depending on which form it is sitting in.

   Do NOT move this to `:focus-visible`. These are text inputs; a pointer user
   who clicks into a field needs the same "you are typing here" answer a
   keyboard user gets, and browsers already treat text fields as always
   focus-visible - the split would only cost contrast, never buy anything. */

   The HUD corner brackets, the ignite beam, the 22px focus bloom and the 1px

   outside the input, and the focus answer is now the contained inset ring in
   the shared block near the top of this file - the same one /register, /forgot
   and /reset get. This is deliberately NOT a login-only treatment any more.

   What survives is the tint, because it sits under the text inside the border
   box and never crosses it. .field keeps `position: relative` only so that a
   future absolutely-positioned child (a reveal-password toggle) has something
   to anchor to; the old `padding: 5px 6px 7px` went with the brackets it was
   making room for, which also makes a login field exactly as wide as the same
   field on /register.
