/* ============================================================
   PULSE-THEME26-V1 — "soft editorial luxury on Pulse indigo"
   Full visual revamp, REVERSIBLE: every rule gated on html.t26
   (class set from the `theme26` Settings row — flip it to "0"
   and the old design returns instantly, no deploy).

   Design language (from the approved references, on purpose):
   editorial whitespace + tight display headings   [LUXURA]
   indigo→lavender gradients, dark-ink stat panels [BloomFi]
   chip metadata + rounded card clusters           [workspace refs]
   large radii 14–20px, pill controls, one accent  [all four]

   SPEED RULES: no fonts, no images, no JS. Transitions are
   transform/opacity/color only (no `all`). backdrop-filter is
   allowed ONLY on overlay chrome (dropdown, modal, chatbot),
   never on cards inside scrolling lists.
