v0.8.0

Upgrading from 0.7

Everything else in 0.8 is additive. These changes need edits in an app built on 0.7:

• A named lc_toggle_group renders native radios. Before: lc_toggle_group(name:) rendered radio
  buttons, a hidden input and the lc-selection controller. After: each item is a label around an
  input type=radio with that name, so listen for the inputs' change instead of lc-selection:change, and
  mark the selected item with checked: or the group's value: instead of selected:. A group without
  name: keeps the radio buttons and lc-selection:change; it no longer has an input target.
• lc_sheet_data is gone. Before: tag.dialog data: lc_sheet_data({ controller: "picker" }, detents: "large").
  After: lc_sheet tag: :dialog, detents: "large", data: { controller: "picker" }. lc_sheet also renders
  non-dialog sheets, so drop any hand-written data-controller="lc-sheet" and handle element too.
• The lc-confirm-dialog controller is gone. Before: a pre-rendered confirm <dialog> wired to
  lc-confirm-dialog. After: render lc_confirm_sheet once in the layout and put data-turbo-confirm on
  the form, with data-turbo-confirm-description, data-turbo-confirm-accept and
  data-turbo-confirm-tone for its description, label and tone.
• A modal lc_dialog is 32rem wide on desktop. Before: min(92vw, 31rem). After: size: :md,
  min(32rem, 100vw - 2rem). Pass size: :sm (24rem) for a narrower dialog, or set --lc-dialog-width.
• lc_dialog puts your content in a body slot. Before: the block rendered straight after the header
  inside [data-slot=dialog-content]. After: it renders inside [data-slot=dialog-body], which scrolls on
  desktop, and the close button sits in [data-slot=dialog-actions]. Update CSS that selects children of
  dialog-content.
• A swiped-away popover sheet hides itself. Before: lc-sheet:dismiss only notified listeners on a
  non-dialog sheet. After: an open [popover] sheet hides unless a listener calls preventDefault().
• An unpadded lc_card no longer gaps its children. Before: lc_card(padding: :none) stacked its
  children --lc-inset apart. After: they meet edge to edge, as rows and empty states in an unpadded card
  expect. Pass class: "gap-inset" to keep the old spacing.
• lc_text(size: :label) is semibold. Before: weight 500. After: 600, the same as a field label, so
  one label role serves both. Add class: "font-medium" where the lighter weight was intended.
