+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.

+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

+    with what it was drawn on. Pure white against v2's canvas, #0E1220, was 18.6:1, where #E3E7F4 had been

     than three colours, and their job is that a glance can tell them apart — so lifting Text and leaving
     TextDim where it was would have widened the first gap and left the second two crowded at the bottom.
-    Every step is raised by roughly what the top gained, which keeps the intervals the design chose and
-    brings the lower steps up to where a secondary label is comfortably readable rather than merely
-    present. TextDim clears 9:1 now, against 6.4:1 before.

+    brought the lower steps up to where a secondary label was comfortably readable rather than merely

+
+    ── v3 ──────────────────────────────────────────────────────────────────────────────────────────────
+    The canvas darkens again, past v2's blue-black to near-black, which raises every one of these ratios
+    again without any of them moving: pure white against the new #05050A canvas is 20.3:1. TextDim,
+    TextFaint and TextGhost are repicked to the design's own neutral-grey values rather than re-derived
+    from v2's blue-tinted ones, because the design supplies its own steps this time — #EDEDF5, #9C9EB4 and
+    #7C7F98 read against the new canvas at roughly 17.5:1, 7.7:1 and 5.2:1, in the same descending order the
+    three names promise. The design also uses two deeper steps, #6D6F84 and #5D5F74, for distinctions this
+    ramp does not yet draw; they are not added as keys until a screen needs them, on the same reasoning as
+    the paragraph above the border ramp — a resource nothing reads is not free, because the next person to
+    touch this file has to work out whether it is dead or merely not yet wired up.

     too pale to carry a button.
 
-    AccentInk is what goes *on* the fill. It equals Canvas today and is named separately anyway, because

+    top-to-bottom gradient rather than a flat fill, lighter violet into the accent proper, and lifts them
+    off the surface with a soft violet-tinted shadow rather than a border. Both are named here rather than
+    inlined in App.axaml for the same reason every other accent value is: one button styled from the wrong

-    green — #3DDC97, for the live dot, the sync light and the follow indicator — and makes the accent blue,
-    which finally separates the two. Live is that green, and nothing that is merely interactive may use it.
+    Blue was the accent through v1 and v2; purple is the accent now. Either way, Ellipse.dot.live keeps its
+    own colour rather than borrowing the accent's, which is the separation this comment originally recorded
+    when the accent first stopped being green: "a shell is open on this host" and "this is the thing the
+    screen wants you to press" read as two different colours by construction, not by coincidence of which
+    two hues the current design happens to pick.

     The three colours that are allowed to disagree with the accent. Amber means a caveat worth reading, red
     means refused or destructive, and blue-light is for the one thing that is neither — an informational log
     line, a directory, a distinct scope.
 
+    Info is left at its v2 value, #7FB0FF, rather than moved: it was already meant to read as distinct from
+    the accent, and now that the accent has moved to purple a blue that used to sit close to it on the wheel
+    sits further from it instead — the separation this colour exists for gets stronger for free.

     WarnText and DangerText are the prose weights: a wash is a very dark tint, and the signal colour that
-    works as a 6-pixel dot or a one-word label is not the one that reads as a sentence on top of it. The
-    design supplies both reds — #E86A6A labels the refusal and #FF8F8F writes it out — and one amber, so
-    the amber prose weight is interpolated.
+    works as a 6-pixel dot or a one-word label is not the one that reads as a sentence on top of it. Danger

+    design's own #F59E0B, and WarnText to the design's own #F5B942 rather than the interpolated value v2

-    The design asks for Instrument Sans and Fira Code, as the one before it asked for IBM Plex. Neither
-    ships with this application, and neither is on a stock Windows install or a stock Android one, so

-    choosing deliberately. Inter is embedded by both heads and is what they already draw with.
+    Montserrat, JetBrains Mono and Material Icons are embedded font files rather than names handed to the
+    font fallback system, and that is a change from every design before this one. v1 asked for IBM Plex,
+    v2 for Instrument Sans and Fira Code, and neither shipped with the application nor came stock on a
+    Windows or an Android install, so requesting either by name would have rendered as whatever fallback
+    the platform chose that day — worse than substituting deliberately. Inter stood in for both heads' sans
+    and the generic `monospace` stood in for the mono stack, and that substitution was the reversible
+    stand-in this comment used to describe.
 
-    The stack ends in the generic `monospace` rather than a Windows face, which is what makes it work on
-    both: Android has no Cascadia Mono or Consolas and resolves the generic name to its own mono face.
-
-    Named as a resource rather than repeated, because the substitution is the sort of thing that gets
-    reversed later and should be reversible in one place. See docs/design-import-gaps.md.
+    It no longer needs to be: the three faces this design names ship as TTFs under Assets/Fonts in this
+    project, embedded the same way WebAssets is, and resolved by the same avares:// URI scheme Inter
+    already used. MonoFont below is JetBrains Mono first, with the old system-mono stack kept after it as a
+    fallback for whatever glyph JetBrains Mono does not cover. IconFont is new: the design's icons are drawn
+    from Material Icons by codepoint rather than by name, and screens adopt that per glyph as they are
+    touched rather than all at once — this resource only makes the face available. Program.cs makes the
+    equivalent change for the sans stack, with Montserrat first and Inter kept as its fallback; see the
+    remarks on BuildAvaloniaApp.
