PKG_NAME:=luci-theme-footstrap
# luci.mk keys the Build/Prepare hook name on LUCI_NAME, which defaults to the checkout's
# directory name — a differently-named checkout symlinked into the feed would silently skip
# the CSS build. Pin it.
LUCI_NAME:=luci-theme-footstrap

# Version is git-derived; never hardcode PKG_VERSION. luci.mk falls back to PKG_SRC_VERSION,
# which it always defines, when nothing here sets it — see docs/package.md for why no override
# lives here.
LUCI_TITLE:=Footstrap Theme
# +luci-base is the WHOLE list. Nothing shipped fetches at run time; `curl` is not in OpenWrt's
# default set (8 MB devices), so fall back to uclient-fetch, jsonfilter, sha256sum or do without.
LUCI_DEPENDS:=+luci-base
LUCI_PKGARCH:=all
# Else luci.mk claims MAINTAINER "OpenWrt LuCI community" and URL openwrt/luci.

# CSS ships verbatim: luci.mk's csstidy mangles :has(), color-mix() and nested calc(). build-css.sh
# minifies.
LUCI_MINIFY_CSS:=0
#
# JS: the released package is built by owfeed (tools/stage.sh), not by this Makefile through the
# SDK, so LUCI_MINIFY_JS keeps luci.mk's jsmin. jsmin's one-character lookback does not know `n` or
# `>`, so `return /re/` makes it eat the rest of the file AND EXIT 0 (openwrt/luci#8299): wrap a
# regex literal there in parentheses.

# Apache-2.0, not a free choice: styles/base began as a fork of luci-theme-bootstrap's cascade.css,
# the ucode templates derive from LuCI's and a few JS helpers are verbatim copies; the notices
# travel with it. No OFL-1.1: the theme ships no Font Software.

# /etc/config/footstrap is SHIPPED as an empty stub and WRITTEN AT RUNTIME: Appearance ->
# "Save as default" has rpcd uci-set the router-wide axes into that very file. Without this define
# the package manager owns it as an ordinary file and REPLACES it on upgrade, so the admin's saved
# defaults are wiped by the theme's own one-click Update, silently and reported as success.
# OpenWrt honours the define for BOTH formats (include/package-pack.mk), so one covers 24.10's opkg
# and 25.12's apk alike. Any future root/etc/config/* must be listed here too.
