* feat(dashboard): rewrite Files-tab sharing as a from-scratch modal
The Files tab's Share… action opened UIWindowShare, a desktop UIWindow,
which doesn't fit the dashboard. Replace it with UIShareModal, built on
the same overlay pattern as UIItemPropertiesModal: a centered card on
desktop, a bottom sheet on mobile, styled with the dashboard's design
tokens (dark mode included).
Wiring follows the onShowProperties precedent: generate_file_context_menu
gains an optional onShare hook that TabFiles supplies; every other caller
falls back to the desktop share window unchanged.
Feature parity with UIWindowShare — grant by email/username with an
access level, list who has access (owner, direct, and inherited-from-
ancestor grants), change a grant's mode, revoke — plus:
- revoke confirmation inlined into the row instead of a stacked UIAlert
- real form semantics: Enter submits, button disabled until input,
spinner while in flight, API errors keep the typed name for correction
- dialog a11y: focus moves in on open and back on close, Tab is trapped,
Escape closes (first Escape cancels an open revoke confirmation),
status messages announce via aria-live
- backdrop close keyed on where the press started, so a text-selection
drag out of the input can't dismiss the dialog
- name-derived avatar colors and a loading state for the first fetch
Also fixes a double-encoding bug (shared by UIWindowShare) where mode
labels ran through html_encode twice, rendering "Can edit & share".
* fix(dashboard): keep keyboard focus inside the share modal across re-renders
Changing a grant's mode, revoking, or Escape-canceling the inline
confirmation re-renders the access list (or disables the focused
control), which dropped focus onto <body> - outside the dialog's Tab
trap and invisible to screen readers. Focus is now restored explicitly
after each of those actions: to the same holder's control when it
survives, else to the dialog itself (tabindex=-1), and the Tab trap
steps back into the cycle when focus rests on the dialog container.
A failed grant likewise returns focus to the recipient input.
* fix(dashboard): give share modal controls 44px touch targets
On touch devices the close (32x32) and revoke (30x30) buttons and the
26px-tall per-row mode select were below the 44px minimum. On coarse
pointers the icon buttons now hit-test at 44x44 through a centered
pseudo-element (visuals unchanged, and the row spacing absorbs the
overhang without overlapping neighbors), and the row select gets
taller padding. Fine-pointer rendering is untouched.
* fix(dashboard): clear the iOS home indicator in the share bottom sheet
The app opts into viewport-fit=cover, so on notched phones the
bottom-docked sheet extends to the physical screen edge and its last
row sat under the home indicator. The sheet body's bottom padding now
adds env(safe-area-inset-bottom), matching how the codebase pads other
bottom-docked surfaces.
* fix(share): say 'Updated access' when changing a grant's mode
Changing someone's access level reported 'Shared with X', the same
message as a fresh grant, which reads as if a new share happened.
Both share dialogs now confirm mode changes with a dedicated
'Updated access for X' message. The UIWindowShare call also drops the
html_encode() around the recipient - i18n() already encodes
interpolations, so the wrapper double-encoded.
* fix(dashboard): align the share dialog's accessible name with the properties modal
The dialog's aria-label read 'name - Share' with an em dash while the
sibling properties modal uses plain 'name Properties'; screen readers
announce the dash as noise. Use the same name-then-noun pattern.
* fix(dashboard): ellipsize the share input's placeholder when it overflows
At phone widths the 'Add people by email or username' placeholder was
clipped mid-letter; text-overflow: ellipsis truncates it cleanly.
* fix(dashboard): raise the share selects' chevron contrast in light mode
The hardcoded slate-400 stroke measured ~2.6:1 against light surfaces,
below the 3:1 minimum for non-text indicators. Light mode now uses
slate-500 (~4.7:1); dark mode keeps slate-400, which already clears
5:1 there.
* fix(dashboard): stop Files-tab shortcuts from firing behind the share modal
The document-level keydown.tabfiles handler kept running while the
share (or item-properties) modal was open. With focus on any of the
modal's buttons or selects, Enter and Space were preventDefault-ed
before they could activate the control, arrows could not drive the
mode selects, and letter typeahead was hijacked into row typesearch —
while Enter opened the selected row behind the overlay, Delete moved
it to Trash, and Cmd+A/C/X/V acted on the hidden list. Yield the
keyboard to the modal for as long as one is up; its own handlers
already cover Escape and Tab.
* fix(dashboard): keep the on-screen keyboard down when the share sheet opens
Autofocusing the recipient input popped the keyboard over the bottom
sheet the moment it opened, hiding the access list before the user had
chosen what to do — the same reason the revoke flow already focuses
the dialog instead of the input. On touch-primary devices give the
dialog container initial focus (which also anchors the Tab trap);
desktop keeps the input autofocus.
* fix(dashboard): give the share sheet's confirm and submit buttons 44px touch height
The inline revoke confirmation's Cancel/Remove pair rendered ~29px
tall on touch — small targets 6px apart where one of the two is
destructive — and the submit button was fixed at 38px. Grow both to
44px under pointer: coarse, matching the standard the modal's icon
buttons already meet. The touch block moves below the confirm-button
base rules it now overrides, since a media query adds no specificity
and source order decides.
* fix(dashboard): name the person in the share rows' accessible labels
Every grant row's mode select announced as bare 'Access level' and
every revoke button as 'Remove access', so a screen reader user
tabbing the list could not tell whose grant a control changes. Carry
the holder in the aria-label ('Access level for alice' / 'Remove
access for alice'); the visible UI and the revoke tooltip stay as
they were. i18n() encodes the interpolated string as a whole, quotes
included, so the labels stay attribute-safe for any holder name.
* fix(dashboard): keep the share status region in the accessibility tree
* fix(dashboard): give the share modal's add-row controls 44px touch height
* refactor(gui): extract the share dialogs' pure logic into tested modules
* feat(dashboard): adopt the shared mode helpers and handle pending invitations
