/* The blog (templates/drobo/blog/index.html, _post.html and _card.html; the top-performer post renders through
_post.html too), in the app frame. Loaded after css/drobo-ui.css, only by blog pages. The Magic UI pieces (dots,
shiny and gradient text, magic card, border beam, blur fade) are the kit's; this file lays them out and sets the
article's type. Every colour comes from the kit's tokens (--ui-*), so light and dark follow the theme.
Made to be read, in dark first (owner, 2026-09-27: "hard to read in dark mode"):
Ground the article is one sheet, a touch lighter than the page in dark, with nothing drawn behind its words
(the header's dots and glow keep to the side that has no text)
Colour headings the brightest; the article's text a soft white in dark (never pure white on black) and near
black in light, 11:1 or more against the sheet; descriptions one step quieter (7:1 or more); the muted
tone only for meta (dates, captions), 4.5:1 or more; links underlined, in the accent that stands clear of
the ground in each theme
Measure the text column is 37rem: about 68 characters of article text a line
Type headings, three sizes: the title (1.9-2.5rem; the index uses the Help center's 2.15-2.9rem), section
headings 1.5rem, sub-headings and card titles 1.125rem. Text: the article 1.0625rem / 1.7 (1rem on phones),
descriptions and notes 1rem and .9375rem, meta and captions .875rem, labels .75rem and .8125rem
Beside the sheet, where the page has the room: "On this page", a plain rail (as on Privacy and Terms); otherwise it
is folded above the sheet.
Motion: the kit's blur fade as a part arrives, a lift of 2-3px on cards, one border beam (the featured post). Nothing
else moves on its own; reduced motion turns all of it off (css/drobo-ui.css).
Behaviour: js/drobo-blog.js (topic filter and search, the section being read, copy link, reading progress). The
page is complete HTML without it. Never write `font: … inherit` shorthands. */
