Schriften ins Repository, Anleitung fuer neue Websites, Schutzkopfzeilen

Die Lato-Dateien liegen jetzt unter public/assets/fonts/ samt OFL-Text
und einer Lizenznotiz: auf einem frischen Server fehlt nichts, und es
wird nie versehentlich von Google geladen.

docs/NEUE-WEBSITE.md beschreibt, wie eine neue Kundenwebsite entsteht -
Reihenfolge, Dokumentformat, Bilder, SEO, Pruefungen - und nennt am
Ende die fuenf Fehler, die hier immer wieder passiert sind.

Permissions-Policy ergaenzt (Kamera, Mikrofon, Standort, Sensoren aus),
X-Powered-By entfernt: der Server nannte in jeder Antwort seine genaue
PHP-Fassung. Die Browserpruefung misst die Kopfzeilen jetzt.

Behoben: der Editor kannte Schema v17, der Validator v18 - die
Beitragsnavigation liess sich in keinem aktuellen Dokument einfuegen.
Ein Test bindet die Zahl des Editors an die des Validators.

+# Schriften in diesem Ordner
+
+Hier liegen die Schriftdateien, die diese Website **selbst ausliefert**. Nichts davon wird zur
+Laufzeit von einem fremden Server geholt: keine Verbindung zu `fonts.googleapis.com`, keine
+IP-Adresse eines Besuchers, die dabei an einen Dritten geht.
+
+## Woher sie kommen
+
+`php bin/console cms:fonts:fetch` (oder der Knopf „Schriften auf diesen Server holen" im
+Designbereich) lädt die im Design gewählten Schnitte einmalig von Google Fonts herunter, behält
+nur die lateinischen Zeichenbereiche und schreibt `fonts.css` mit den passenden
+`@font-face`-Regeln daneben.
+
+## Lizenz
+
+**Lato** steht unter der SIL Open Font License 1.1 – der vollständige Text liegt als
+`lato-OFL.txt` daneben, wie die Lizenz es verlangt. Copyright (c) 2010–2014 tyPoland Łukasz
+Dziedzic, Reserved Font Name „Lato". Die Lizenz erlaubt ausdrücklich, die Dateien mitzuliefern und
+von einem eigenen Server auszuliefern; verboten ist der Verkauf der Schrift für sich genommen und
+die Verwendung des reservierten Namens für eine geänderte Fassung.
+
+Wer hier andere Schriften ablegt, prüft deren Lizenz selbst: nicht jede Schrift, die Google Fonts
+ausliefert, steht unter der OFL – einige stehen unter der Apache-Lizenz 2.0, und eine gekaufte
+Schrift eines Schriftenhauses darf meist gar nicht weitergegeben werden. Die Lizenzdatei gehört in
+jedem Fall daneben.

+Copyright (c) 2010-2014 by tyPoland Lukasz Dziedzic (team@latofonts.com) with Reserved Font Name "Lato"
+
+This Font Software is licensed under the SIL Open Font License, Version 1.1.
+This license is copied below, and is also available with a FAQ at:
+http://scripts.sil.org/OFL
+
+
+-----------------------------------------------------------
+SIL OPEN FONT LICENSE Version 1.1 - 26 February 2007
+-----------------------------------------------------------
+
+PREAMBLE
+The goals of the Open Font License (OFL) are to stimulate worldwide
+development of collaborative font projects, to support the font creation
+efforts of academic and linguistic communities, and to provide a free and
+open framework in which fonts may be shared and improved in partnership
+with others.
+
+The OFL allows the licensed fonts to be used, studied, modified and
+redistributed freely as long as they are not sold by themselves. The
+fonts, including any derivative works, can be bundled, embedded, 
+redistributed and/or sold with any software provided that any reserved
+names are not used by derivative works. The fonts and derivatives,
+however, cannot be released under any other type of license. The
+requirement for fonts to remain under this license does not apply
+to any document created using the fonts or their derivatives.
+
+DEFINITIONS
+"Font Software" refers to the set of files released by the Copyright
+Holder(s) under this license and clearly marked as such. This may
+include source files, build scripts and documentation.
+
+"Reserved Font Name" refers to any names specified as such after the
+copyright statement(s).
+
+"Original Version" refers to the collection of Font Software components as
+distributed by the Copyright Holder(s).
+
+"Modified Version" refers to any derivative made by adding to, deleting,
+or substituting -- in part or in whole -- any of the components of the
+Original Version, by changing formats or by porting the Font Software to a
+new environment.
+
+"Author" refers to any designer, engineer, programmer, technical
+writer or other person who contributed to the Font Software.
+
+PERMISSION & CONDITIONS
+Permission is hereby granted, free of charge, to any person obtaining
+a copy of the Font Software, to use, study, copy, merge, embed, modify,
+redistribute, and sell modified and unmodified copies of the Font
+Software, subject to the following conditions:
+
+1) Neither the Font Software nor any of its individual components,
+in Original or Modified Versions, may be sold by itself.
+
+2) Original or Modified Versions of the Font Software may be bundled,
+redistributed and/or sold with any software, provided that each copy
+contains the above copyright notice and this license. These can be
+included either as stand-alone text files, human-readable headers or
+in the appropriate machine-readable metadata fields within text or
+binary files as long as those fields can be easily viewed by the user.
+
+3) No Modified Version of the Font Software may use the Reserved Font
+Name(s) unless explicit written permission is granted by the corresponding
+Copyright Holder. This restriction only applies to the primary font name as
+presented to the users.
+
+4) The name(s) of the Copyright Holder(s) or the Author(s) of the Font
+Software shall not be used to promote, endorse or advertise any
+Modified Version, except to acknowledge the contribution(s) of the
+Copyright Holder(s) and the Author(s) or with their explicit written
+permission.
+
+5) The Font Software, modified or unmodified, in part or in whole,
+must be distributed entirely under this license, and must not be
+distributed under any other license. The requirement for fonts to
+remain under this license does not apply to any document created
+using the Font Software.
+
+TERMINATION
+This license becomes null and void if any of the above conditions are
+not met.
+
+DISCLAIMER
+THE FONT SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND,
+EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY WARRANTIES OF

+DAMAGES, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING
+FROM, OUT OF THE USE OR INABILITY TO USE THE FONT SOFTWARE OR FROM
+OTHER DEALINGS IN THE FONT SOFTWARE.
