lum_glyph
Unlit HDR glow shader for the lumen opener's lettering
(preseed/parts/p1_lumen). Renders mix(color, hot_color, heat) * intensity
with a view-rim lift and a slow vertical shimmer, so a driven intensity
takes a glyph mesh from ember-dark to bloom-hot without touching the lit
PBR layer in front of it. Material instances: lum_glyph_mat (the title's
driven back-glow) and lum_glyph_sub_mat (the subtitle's static soft glow).
