Show MPRIS now-playing and upower battery under the clock, polled on a
background thread (zbus). Flags gate both drawing and D-Bus; desktops
without a battery stay blank; titles are truncated.
Also the locker audit pass that landed in the same files:
- PAM authenticates getuid()/getpwuid_r, not $USER, and missing
username still takes the lock
- one lock surface per output, generation-gated fail timers, PAM
timeout, Tab-reveal off by default and cleared on keyboard leave
- GPU chrome is a dirty-rect quad with EGL cleanup; shm reuses a
SlotPool; appear/shake/flash/veil/clock-crossfade bugs
- hold-to-reveal, checking ellipsis, and password display length
Live-checked on hermes (GPU path, PAM unlock, Tab-hold).
Four lock-screen niceties:
- Caps Lock / layout chip: a small pill above the password pill shows
when Caps Lock is on or a non-default layout is selected, so all-caps
input never mystifies.
- Hold-to-reveal: holding Tab renders the plain password instead of
dots (Tab produces no utf8, so it can never be part of the password).
- Idle auto-dim: after `animation.idle_dim_after_secs` of no keystrokes
the dim veil deepens past the base gradient (background-only alpha can
legally exceed 1.0), ramping over a few seconds for OLED/burn-in
comfort. Shared `veil_alpha` keeps software and GPU paths identical.
- Attempt counter: repeat failures show "Wrong password — N failed
attempts" so a stuck locker reads differently from ordinary typos.
All four render paths covered by tests (veil math, reveal truncation,
chip/reveal compose) and live-verified in nested Hyprland on the GPU
path; idle dim confirmed to deepen the veil (84.5->75.8 top).
Adds a full motion system to the lock screen (staggered entrance, dot pop
+ caret, wrong-password shake, success flash, clock crossfade), depth
polish (gradient veil, pill shadow + hairline border, "Enter password"
hint, responsive typography), and a second wave of animations (idle
breathing, success dot cascade, status slide-in, parallax unlock drift,
animated checking ellipsis, opt-in Ken Burns wallpaper pan). Includes a
dev-only breadlock-preview harness that renders every state to PNGs with
no Wayland involved, and a design/sketch.html prototype.
Fixes text alpha being dropped by cosmic-text's glyph-mask path (all text
fades now work) and double-drifting that made the date/status overlap the
clock/pill during unlock.
