-- YataiDON-HSS override of PyTaikoGreen/global/allnet_indicator.lua
-- ROUND 6 (LUA_CAPABILITIES item 43) — boot-loading chrome.
--
-- `AllNetIcon:draw` is the last Lua call on LOADING (loading.cpp: black fill, progress-bar
-- track + fill, KIDOU::WARNING, white fade, allnet_indicator.draw), so it is the skin's only
-- paint hook on the boot screen.
--
-- Arcade reference: lumen attract/notice, `notice_instance_0` at (959.7,542.4) —
--   d0 8x8 black stretched 240x135  -> 1920x1080 backdrop            (engine: DrawRectangle BLACK)
--   d1 NOTICE board 846x886 @ (0,-46) -> top-left (536.7, 53.4)      (kidou/warning)
--   d2 8x8 #650000 stretched 115.47x5 -> a 923.7x40 track @ (497.9, 977.1)
--   d3 8x8 #ff0000 stretched  0.50x5 -> the fill, left-anchored at x 494.7, growing to 923.7
--   d4/d5 two 62x49.5 black caps at the ends of the track (invisible on black)
--   d6 8x8 white stretched 240x135, alpha 0 -> the fade-out          (engine: Fade(WHITE, …))
-- The engine already copies the arcade's exact colours (101,0,0 / RED) and the white fade;
-- what it cannot match from a skin is the GEOMETRY: `progress_bar_*` in LoadingScreen::
-- on_screen_start is derived from the screen metrics (0.43*W x 50*scale at y = 0.85*H =
-- 825.6x75 @ (547.2, 918)) and `progress` has no Lua binding, so the bar cannot be redrawn
-- here. Its top edge (918) lands 11 px inside the last NOTICE line (ink bottom 929 with the
-- arcade board position restored in kidou/texture.json), so the board is simply re-drawn on
-- top from here — in the arcade the two never overlap (board ends 939.4, track starts 977.1),
-- so the stacking is unobservable there and this restores the readable result.
--
-- The ALL.Net icon itself is skipped on LOADING: the arcade boot notice screen carries no
-- overlay at all, and the engine draws this icon AFTER its white fade-out, so it would
-- otherwise hang in front of the full-white flash into the title screen.
